羊腫瘤壞死因子α試劑盒注意事項
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zui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。

Mouse Tumor necrosis factor α
| FOR RESEARCH USE ONLY |
Assay range：25ng/L -800ng/L 96 determinations
Purpose
This kit allows for the determination of TNF-α concentrations in Mouse serum, cell culture supernates and other biological fluids
Principle of the assay
The kit assay Mouse TNF-α level in the sample，use Purified Mouse TNF-α antibody to coat microtiter plate wells, make solid-phase antibody, then add TNF-α to wells, Combined antibody which With HRP labeled goat anti-mouse become antibody - antigen - enzyme-antibody complex, after washing Compley, 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 TNF-α in the samples is then determined by comparing the O.D. of the samples to the standard curve.

| 50 ng/L | 1 Standard | 150μl 2 Standard +150μl Standard diluent |
2.add sample：Set blank wells separay （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.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30 min at
4.Configurate liquid: 30-fold wash solution diluted 30-fold （or 20-fold） with distilled water and reserve.
5.washing：Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer 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
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.

Take the standard density as the horizontal, the OD value for the vertical ,draw the standard curve on graph paper, Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilution factor, the result is the sample actual density.
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.
9. Do not mix reagents with those from other lots.
