Rat Ultra Sensitive Heat Shock
Protein 70,HSP-70
ELISA Kit
(96 T)
This immunoassay kit allows for the in vitro quantitative determination of rat
HSP-70 concentrations in serum, plasma and other biological fluids.
Expiration date six months from the date of manufacture
FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC PROCEDURES.
PRINCIPLE OF THE ASSAY
The microtiter plate provided in this kit has been pre-coated with
an antibody specific to HSP-70. Standards or samples are then
added to the appropriate microtiter plate wells with a
biotin-conjugated antibody preparation specific for HSP-70 and
Avidin conjugated to Horseradish Peroxidase (HRP) is added to
each microplate well and incubated. Then a TMB (3,3,5,5
tetramethyl-benzidine) substrate solution is added to each well.
Only those wells that contain HSP-70, biotin-conjugated antibody
and enzyme-conjugated Avidin will exhibit a change in color. The
enzyme-substrate reaction is terminated by the addition of a
sulphuric acid solution and the color change is measured
spectrophotometrically at a wavelength of 450 nm ± 2 nm. The
concentration of HSP-70 in the samples is then determined by
comparing the O.D. of the samples to the standard curve.
DETECTION RANGE
39 pg/ml-2500 pg/ml. The standard curve concentrations used
for the ELISA’s were 2500 pg/ml, 1250 pg/ml, 625 pg/ml, 312
pg/ml, 156 pg/ml, 78 pg/ml, 39 pg/ml.
SPECIFICITY
This assay recognizes recombinant and natural rat HSP-70. No
significant cross-reactivity or interference was observed.
SENSITIVITY
The minimum detectable dose of rat HSP-70 is typically less
than 9.8 pg/ml.
The sensitivity of this assay, or Lower Limit of Detection (LLD)
was defined as the lowest protein concentration that could be
differentiated from zero.

STORAGE
1. Unopened test kits should be stored at 2-8°C upon receipt
and the microtiter plate should be kept in a sealed bag. The
test kit may be used throughout the expiration date of the kit,
provided it is stored as prescribed above. Refer to the
package label for the expiration date.
2. Opened test plate should be stored at 2-8°C in the aluminum
foil bag with desiccants to minimize exposure to damp air. The
kits will remain stable until the expiring date shown, provided it
is stored as prescribed above.
3. A microtiter plate reader with a bandwidth of 10 nm or less
and an optical density range of 0-3 OD or greater at 450nm
wavelength is acceptable for use in absorbance
measurement.
REAGENT PREPARATION
Bring all reagents to room temperature before use.
1. Wash Buffer If crystals have formed in the concentrate,
warm up to room temperature and mix gently until the
crystals have completely dissolved. Dilute 20 ml of Wash
Buffer Concentrate into deionized or distilled water to prepare
500 ml of Wash Buffer.
2. Standard Centrifuge the standard vial at 6000-10000rpm
for 30s. Reconstitute the Standard with 1.0 ml of Sample
Diluent. This reconstitution produces a stock solution of 2500
pg/ml. Allow the standard to sit for a minimum of 15 minutes
with gentle agitation prior to making serial dilutions. The
undiluted standard serves as the high standard (2500 pg/ml).
The Sample Diluent serves as the zero standard (0 pg/ml).
Prepare fresh for each assay. Use within 4 hours and discard
after use.
3. Biotin-antibody Centrifuge the vial before opening. Dilute
to the working concentration using Biotin-antibody
Diluent(1:100), respectively.
4. HRP-avidin Centrifuge the vial before opening. Dilute to the
working concentration using HRP-avidin Diluent(1:100),
respectively.
Precaution: The Stop Solution provided with this kit is an acid solution. Wear
eye, hand, face, and clothing protection when using this material.
OTHER SUPPLIES REQUIRED
Microplate reader capable of measuring absorbance at 450
nm, with the correction wavelength set at 540 nm or 570 nm.
Pipettes and pipette tips.
Deionized or distilled water.
Squirt bottle, manifold dispenser, or automated microplate
washer.
An incubator which can provide stable incubation conditions
up to 37°C ±0.5°C.
SAMPLE COLLECTION AND STORAGE
Serum Use a serum separator tube (SST) and allow
samples to clot for 30 minutes before centrifugation for 15
minutes at 1000 g. Remove serum and assay immediately or
aliquot and store samples at -20°C. Centrifuge the sample
again after thawing before the assay. Avoid repeated
freeze-thaw cycles.
Plasma Collect plasma using citrate, EDTA, or heparin as
an anticoagulant. Centrifuge for 15 minutes at 1000 g within
30 minutes of collection. Assay immediately or aliquot and
store samples at -20°C. Centrifuge the sample again after
thawing before the assay. Avoid repeated freeze-thaw cycles.
Note: Grossly hemolyzed samples are not suitable for use in this assay.
ASSAY PROCEDURE
Bring all reagents and samples to room temperature before use. It is
recommended that all samples, standards, and controls be assayed in duplicate.
All the reagents should be added directly to the liquid level in the well. The
pipette should avoid contacting the inner wall of the well.
1. Serum and plasma samples require a 20-fold dilution into
Sample Diluent. The suggested 20-fold dilution can be
achieved by adding 15μl sample to 285μl of Sample Diluent.
2. Add 100μl of Standard, Blank, or Sample per well. Cover with
the adhesive strip. Incubate for 2 hours at 37°C.
3. Remove the liquid of each well, don’t wash.
4. Add 100μl of Biotin-antibody working solution to each well.
Incubate for 1 hour at 37°C. Biotin-antibody working
solution may appear cloudy. Warm up to room temperature
and mix gently until solution appears uniform.
5. Aspirate each well and wash, repeating the process three
times for a total of three washes. Wash: Fill each well with
Wash Buffer (200μl) and let it stand for 2 minutes, then
remove the liquid by flicking the plate over a sink. The
remaining drops are removed by patting the plate on a paper
towel. Complete removal of liquid at each step is essential to
good performance.
6. Add 100μl of HRP-avidin working solution to each well.
Cover the microtiter plate with a new adhesive strip. Incubate
for 1 hour at 37°C.
7. Repeat the aspiration and wash five times as step 4.
8. Add 90μl of TMB Substrate to each well. Incubate for 10-30
minutes at 37°C. Keeping the plate away from drafts and
other temperature fluctuations in the dark.
9. Add 50μl of Stop Solution to each well when the first four
wells containing the highest concentration of standards
develop obvious blue color. If color change does not appear
uniform, gently tap the plate to ensure thorough mixing.
10. Determine the optical density of each well within 30 minutes,
using a microplate reader set to 450 nm.
CALCULATION OF RESULTS
Using the professional soft "Curve Exert 1.3" to make a standard curve is
recommended, which can be downloaded from our web.
Average the duplicate readings for each standard, control, and
sample and subtract the average zero standard optical density.
Create a standard curve by reducing the data using computer
software capable of generating a four parameter logistic (4-PL)
curve-fit. As an alternative, construct a standard curve by plotting
the mean absorbance for each standard on the y-axis against
the concentration on the x-axis and draw a best fit curve through
the points on the graph. The data may be linearized by plotting
the log of the HSP-70 concentrations versus the log of the O.D.
and the best fit line can be determined by regression analysis.
This procedure will produce an adequate but less precise fit of
the data. If samples have been diluted, the concentration read
from the standard curve must be multiplied by the dilution factor.
LIMITATIONS OF THE PROCEDURE
The kit should not be used beyond the expiration date on the
kit label.
Do not mix or substitute reagents with those from other lots or
sources.
It is important that the Standard Diluent selected for the
standard curve be consistent with the samples being
assayed.
If samples generate values higher than the highest standard,
dilute the samples with the appropriate Standard Diluent and
repeat the assay.
Any variation in Standard Diluent, operator, pipetting
technique, washing technique, incubation time or
temperature, and kit age can cause variation in binding.
This assay is designed to eliminate interference by soluble
receptors, binding proteins, and other factors present in
biological samples. Until all factors have been tested in the
Quantikine Immunoassay, the possibility of interference
cannot be excluded.
TECHNICAL HINTS
Centrifuge vials before opening to collect contents.
When mixing or reconstituting protein solutions, always avoid
foaming.
To avoid cross-contamination, change pipette tips between
additions of each standard level, between sample additions,
and between reagent additions. Also, use separate reservoirs
for each reagent.
When using an automated plate washer, adding a 30 second
soak period following the addition of wash buffer, and/or
rotating the plate 180 degrees between wash steps may
improve assay precision.
To ensure accurate results, proper adhesion of plate sealers
during incubation steps is necessary.
Substrate Solution should remain colorless or light blue until
added to the plate. Keep Substrate Solution protected from
light. Substrate Solution should change from colorless or light
blue to gradations of blue.
Stop Solution should be added to the plate in the same order
as the Substrate Solution. The color developed in the wells
will turn from blue to yellow upon addition of the Stop Solution.
Wells that are green in color indicate that the Stop Solution
has not mixed thoroughly with the Substrate Solution.

解凍後的樣品應再次離心，然後檢測。
註：標本溶血會影響最後檢測結果，因此溶血標本不宜進行此項檢測。
標本的稀釋原則：
首先通過文獻檢索的方式了解待測樣本的大致含量，確定適當的稀釋倍數。
只有稀釋至標準曲線的範圍內，檢測的結果才是準確的。稀釋的過程中，應
做好詳細的記錄。最後計算濃度時，稀釋了「N」倍，標本的濃度應再乘以「N」。
標準品的稀釋原則：2 瓶，使用前於6000-10000rpm 離心30 秒。每
瓶臨用前以樣品稀釋液稀釋至1ml，蓋好後靜置10 分鐘以上，然後反覆顛倒
/搓動以助溶解，其濃度為2500 pg/ml，做系列倍比稀釋後，分別稀釋2500
pg/ml, 1250 pg/ml, 625 pg/ml, 312 pg/ml, 156 pg/ml, 78 pg/ml, 39 pg/ml，樣
品稀釋液直接作為標準濃度0 pg/ml，臨用前15 分鐘內配製，用完丟棄，下
次檢測使用新鮮配置的標準品。
如配製1250 pg/ml 標準品：取0.5ml（不要少於0.5ml）2500 pg/ml 的上述
標準品加入含0.5ml 樣品稀釋液的Eppendorf 管中，混勻即可，其餘濃度以
此類推。
生物素標記抗體的稀釋原則：
打開瓶蓋前請離心，收集瓶壁上的溶液。臨用前以生物素標記抗體稀釋液稀
釋，稀釋前根據預先計算好的每次實驗所需的總量配製（每孔100μl），實際
配製時應多配製0.1-0.2ml。如10μl 生物素標記抗體加990μl 生物素標記抗體
稀釋液的比例配製，輕輕混勻，在使用前一小時內配製。
辣根過氧化物酶標記親和素的稀釋原則：
打開瓶蓋前請離心，收集瓶壁上的溶液。臨用前以辣根過氧化物酶標記親和
素稀釋液稀釋，稀釋前根據預先計算好的每次實驗所需的總量配製（每孔
100μl），實際配製時應多配製0.1-0.2ml。如10μl 辣根過氧化物酶標記親和素
加990μl 辣根過氧化物酶標記親和素稀釋液的比例配製，輕輕混勻，在使用
前一小時內配製。
操作步驟
實驗開始前，請提前配置好所有試劑，試劑或樣品稀釋時，均需混勻，混勻
時儘量避免起泡。每次檢測都應該做標準曲線。如樣品濃度過高時，用樣品
稀釋液進行稀釋，以使樣品符合試劑盒的檢測範圍。加樣時，槍頭應直接對
準液面，切勿沿孔壁加樣。
4. 血清，血漿樣本用樣本稀釋液進行1:20 倍稀釋後進行檢測，具體操作如
下：取15μl 樣本加入到285μl 的樣本稀釋液（1:20 稀釋）中混勻。得
到的即為1:20 倍稀釋後的樣本。
5. 加樣：分別設空白孔、標準孔、待測樣品孔。空白孔加樣品稀釋液100μl，
餘孔分別加標準品或待測樣品100μl，注意不要有氣泡，加樣將樣品加於
酶標板孔底部，儘量不觸及孔壁，輕輕晃動混勻，酶標板加上蓋或覆膜，
37℃反應120 分鐘。
為保證實驗結果有效性，每次實驗請使用新的標準品溶液。
6. 棄去液體，甩幹，不用洗滌。每孔加生物素標記抗體工作液 100μl（取1μl
生物素標記抗體加99μl 生物素標記抗體稀釋液的比例配製，輕輕混勻，
在使用前一小時內配製），37℃,60 分鐘。
7. 溫育60 分鐘後，棄去孔內液體，甩幹，洗板3 次，每次浸泡1-2 分鐘，
200μl/每孔，甩幹。
8. 每孔加辣根過氧化物酶標記親和素工作液（同生物素標記抗體工作液）
100μl，37℃，60 分鐘。
9. 溫育60 分鐘後，棄去孔內液體，甩幹，洗板5 次，每次浸泡1-2 分鐘，
200μl/每孔，甩幹。
10. 依序每孔加底物溶液90μl，37℃避光顯色（30 分鐘內，此時肉眼可見標
準品的前3-4 孔有明顯的梯度藍色，後3-4 孔顯色不明顯，即可終止）。
11. 依序每孔加終止溶液50μl，終止反應（此時藍色立轉黃色）。終止液的加
入順序應儘量與底物液的加入順序相同。為了保證實驗結果的準確性，底
物反應時間到後應儘快加入終止液。
12. 用酶聯儀在450nm 波長依序測量各孔的光密度（OD 值）。在加終止液
後15 分鐘以內進行檢測。
實驗備註
1. 用戶在初次使用試劑盒時，應將各種試劑管離心數分鐘，以便試劑集中到
管底。
2. 每次實驗留一孔作為空白調零孔，該孔不加任何試劑，只是最後加底物溶
液及終止液。測量時先用此孔調OD 值至零。
3. 為防止樣品蒸發，試驗時將反應板放於鋪有溼布的密閉盒內，酶標板加上
蓋或覆膜。
4. 未使用完的酶標板或者試劑，請於2-8℃保存。標準品、生物素標記抗體
工作液、辣根過氧化物酶標記親和素工作液請依據所需的量配置使用。請
勿重複使用已稀釋過的標準品、生物素標記抗體工作液、或辣根過氧化物
酶標記親和素工作液。
5. 建議檢測樣品時均設雙孔測定，以保證檢測結果的準確性。
洗板方法
手工洗板方法：吸去（不可觸及板壁）或甩掉酶標板內的液體；在實驗臺上
鋪墊幾層吸水紙，酶標板朝下用力拍幾次；將推薦的洗滌緩衝液至少0.3ml
注入孔內，浸泡1-2 分鐘。根據需要，重複此過程數次。
自動洗板：如果有自動洗板機，應在熟練使用後再用到正式實驗過程中。
計算
請從我們的網站下載專業軟體"Curve Exert 1.3"，並根據提示製作標準曲線。
以標準物的濃度為橫坐標（對數坐標），OD 值為縱坐標（普通坐標），在半對
數坐標紙上繪出標準曲線，根據樣品的OD 值由標準曲線查出相應的濃度；
再乘以稀釋倍數；或用標準物的濃度與OD 值計算出標準曲線的直線回歸方
程式，將樣品的OD 值代入方程式，計算出樣品濃度，再乘以稀釋倍數，即
為樣品的實際濃度。
注意事項
1. 本操作說明適用於48T試劑盒， 48T試劑盒中酶聯板、標準品、生物素
標記抗體及辣根過氧化物酶標記親和素減半。
2. 當混合蛋白溶液時應儘量輕緩，避免起泡。
3. 洗滌過程非常重要，不充分的洗滌易造成假陽性。
4. 一次加樣時間最好控制在5 分鐘內，如標本數量多，推薦使用排槍加樣。
5. 請每次測定的同時做標準曲線，最好做復孔。
6. 如標本中待測物質含量過高，請先稀釋後再測定，計算時請最後乘以稀釋
倍數。
7. 在配製標準品、檢測溶液工作液時，請以相應的稀釋液配製，不能混淆。
8. 底物請避光保存。
9. 不要用其它生產廠家的試劑替換試劑盒中的試劑。
