小鼠胰島素（Insulin）酶聯免疫分析（ELISA）試劑盒使用說明書本試劑僅供研究使用目的：本試劑盒用于測定小鼠血清樣本中胰島
素（Insulin）含量。
實驗原理：
本試劑盒應用雙
抗體夾心法測定標本中小鼠胰島素（Insulin）水平。用純化的小鼠胰島素（Insulin）抗體包被微孔板，制成固相抗體，往包被單抗的微孔中依次加入胰島素（Insulin），再與HRP 標記的胰島素（Insulin）抗體結合，形成抗體-抗原-酶標抗體復合物，經過徹底洗滌后加底物TMB 顯色。TMB 在HRP 酶的催化下轉化成藍色，并在酸的作用下轉化成*終的黃色。顏色的深淺和樣品中的胰島素（Insulin）呈正相關。用酶標儀在450nm 波長下測定吸光度（OD 值），通過標準曲線計算樣品中小鼠胰島素（Insulin）含量。

樣本處理及要求：
1. 血清：室溫血液自然凝固10-20 分鐘，離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清，保存過程中如出現沉淀，應再次離心。
2. 血漿：應根據標本的要求選擇EDTA、檸檬酸鈉或肝素作為抗凝劑，混合10-20 分鐘后，離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清，保存過程中如有沉淀形成，應該再次離心。
3. 尿液：用無菌管收集，離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清，保存過程
中如有沉淀形成，應再次離心。胸腹水、腦脊液參照實行。
4.
細胞培養上清：檢測分泌性的成份時，用無菌管收集。離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清。檢測細胞內的成份時，用PBS（PH7.2-7.4）稀釋細胞懸液，細胞濃度達到100 萬/ml 左右。通過反復凍融，以使細胞破壞并放出細胞內成份。離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清。保存過程中如有沉淀形成，應再次離心。

5. 組織標本：切割標本后，稱取重量。加入一定量的PBS，PH7.4。用液氮迅速冷凍保存備用。標本融化后仍然保持2-8℃的溫度。加入一定量的PBS（PH7.4），用手工或勻漿器將標本勻漿充分。離心20 分鐘左右（2000-3000 轉/分）。仔細收集上清。分裝后一份待檢測，其余冷凍備用。
6. 標本采集后盡早進行提取，提取按相關文獻進行，提取后應盡快進行實驗。若不能馬上進行試驗，可將標本放于-20℃保存，但應避免反復凍融.
7. 不能檢測含NaN3 的樣品，因NaN3 抑制辣根過氧化物酶的（HRP）活性。
操作步驟
1. 標準品的稀釋與加樣：在酶標包被板上設標準品孔10 孔，在、第二孔中分別加標準品100μl，然后在、第二孔中加標準品稀釋液50μl，混勻；然后從孔、第二孔中各取100μl 分別加到第三孔和第四孔，再在第三、第四孔分別加標準品稀釋液50μl，混勻；然后在第三孔和第四孔中先各取50μl 棄掉，再各取50μl 分別加到第五、第六孔中，再在第五、第六孔中分別加標準品稀釋液50ul，混勻；混勻后從第五、第六孔中各取50μl 分別加到第七、第八孔中，再在第七、第八孔中分別加標準品稀釋液50μl，混勻后從第七、第八孔中分別取50μl 加到第九、第十孔中，再在第九第十孔分別加標準品稀釋液50μl，混勻后從第九第十孔中各取50μl 棄掉。（稀釋后各孔加樣量都為50μl，濃度分別為12 mIU/L，8.0 mIU/L ，4.0 mIU/L，2.0 mIU/L，1.0 mIU/L）。
2. 加樣：分別設空白孔（空白對照孔不加樣品及酶標試劑，其余各步操作相同）、待測樣品孔。在酶標包被板上待測樣品孔中先加樣品稀釋液40μl，然后再加待測樣品10μl（樣品*終稀釋度為5 倍）。加樣將樣品加于酶標板孔底部，盡量不觸及孔壁，輕輕晃動混勻。
3. 溫育：用封板膜封板后置37℃溫育30 分鐘。
4. 配液：將30（48T 的20 倍）倍濃縮洗滌液用蒸餾水30（48T 的20 倍）倍稀釋后備用。
5. 洗滌：小心揭掉封板膜，棄去液體，甩干，每孔加滿洗滌液，靜置30 秒后棄去，如此重復5 次，拍干。
6. 加酶：每孔加入酶標試劑50μl，空白孔除外。
7. 溫育：操作同3。
8. 洗滌：操作同5。
9. 顯色：每孔先加入顯色劑A50μl，再加入顯色劑B50μl，輕輕震蕩混勻，37℃避光顯色15 分鐘.
10. 終止：每孔加終止液50μl，終止反應（此時藍色立轉黃色）。
11. 測定：以空白空調零，450nm 波長依序測量各孔的吸光度（OD 值）。測定應在加終止液后15 分鐘以內進行。
注意事項：
1． 試劑盒從冷藏環境中取出應在室溫平衡15-30 分鐘后方可使用，酶標包被板開封后如未用完，板條應裝入密封袋中保存。
2． 濃洗滌液可能會有結晶析出，稀釋時可在水浴中加溫助溶，洗滌時不影響結果。
3． 各步加樣均應使用加樣器，并經常校對其準確性，以避免試驗誤差。一次加樣時間控制在5 分鐘內，如標本數量多，推薦使用排槍加樣。
4． 請每次測定的同時做標準曲線，做復孔。如標本中待測物質含量過高（樣本OD 值大于標準品孔孔的OD 值），請先用樣品稀釋液稀釋一定倍數（n 倍）后再測定，計算時請*后乘以總稀釋倍數（×n×5）。
5． 封板膜只限一次性使用，以避免交叉污染。
6． 底物請避光保存。
7． 嚴格按照說明書的操作進行，試驗結果判定必須以酶標儀讀數為準.
8． 所有樣品，洗滌液和各種廢棄物都應按傳染物處理。
9． 本試劑不同批號組分不得混用。
10. 如與英文說明書有異，以英文說明書為準。
計算：
以標準物的濃度為橫坐標，OD 值為縱坐標，
在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。

This kit allows for the determination of Insulin concentrations in Mouse serum ａnd other
biological fluids.
Principle of the assay
The kit assay Mouse Insulin level in the sample, use Purified Mouse Insulin antibody to
coat microtiter plate wells, make solid-phase antibody, then add Insulin to wells, Combined
Insulin antibody which With HRP labeled, become antibody - antigen - enzyme-antibody
complex, after washing Completely, Add TMB substrate solution,TMB substrate becomes blue
color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid
solution ａnd the color change is measured spectrophotometrically at a wavelength of 450 nm.
The concentration of Mouse Insulin in the samples is then determined by comparing the O.D. of
the samples to the standard curve.

Assay procedure
1.Dilute ａnd add sample to Standard: set 10 Standard wells on the ELISA plates coated, add
Standard 100μl to the first ａnd the second well, then add Standard dilution 50μl to the first and
the second well, mix; take out 100μl form the first ａnd the second well then add it to the third
and the forth well separately. then add Standard dilution 50μl to the third ａnd the forth
well ,mix ; then take out 50μl from the third ａnd the forth well discard, add 50μl to the fifth and
the sixth well ,then add Standard dilution 50μl to the fifth ａnd the sixth well, mix ; take out 50μl
from the fifth ａnd the sixth well ａnd add to the seventh ａnd the eighth well, then add Standard
dilution 50μl to the seventh ａnd the eighth well ,mix ; take out 50μl from the seventh ａnd the
eighth well ａnd add to the ninth ａnd the tenth well, add Standard dilution 50μl to the ninth and

each well after Diluting ,（density: 12 mIU/L,8.0 mIU/L ,4.0 mIU/L,2.0 mIU/L,1.0 mIU/L）
2.add sample ： Set blank wells separately （blank comparison wells don’t add sample and
HRP-Conjugate reagent, other each step operation is same）. testing sample well. add Sample
dilution 40μl to testing sample well, then add testing sample 10μl （sample final dilution is
5-fold）, add sample to wells , don’t touch the well wall as far as possible, ａnd Gently mix.

water ａnd reserve.
5.washing：Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer
7
to every well, still for 30s then drain, repeat 5 times, dry by pat.
6.add enzyme：Add HRP-Conjugate reagent 50μl to each well, except blank well.
7.incubate：Operation with 3.
8.washing：Operation with 5.
9.color：Add Chromogen Solution A 50ul ａnd Chromogen Solution B to each well, evade the
light preservation for 15 min at 37℃
10.Stop the reaction ： Add Stop Solution50μl to each well, Stop the reaction（the blue color
change to yellow color）.
11.assay：take blank well as zero , Read absorbance at 450nm after Adding Stop Solution and
within 15min.
Important notes
1. The kit takes out from the refrigeration environment should be balanced 15-30 minutes in
the room temperature, ELISA plates coated if has not use up after opened, the plate should
be stored in Sealed bag.
2. washing buffer will Crystallization separation, it can be heated the water helps dissolve
when dilute . Washing does not affect the result.
3. add Sample with sampler Each step, And proofread its accuracy frequently, avoids the
experimental error. add sample within 5 min, if the number of sample is much , recommend
to use Volley .
4. if the testing material content is excessively higher （The sample OD is bigger than the first
standard well ）,please dilute Sample （n-fold）, Please diluente ａnd multiplied by the dilution
factor.（×n×5）.
5. Closure plate membrane only limits the disposable use, to avoid cross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly, The test result determination must take the
microtiter plate reader as a standard.
8. All samples, washing buffer ａnd each kind of reject should according to infective material
process.
