试剂盒使用说明书
本试剂仅供研究使用 目的：本试剂盒用于测定人血清，血浆及相关液体样本中蛋白C（PC）的含量。本公司专业供应Elisa试剂盒，*，*，可免费提供代测服务，咨询：， :
实验原理：
本试剂盒应用双抗体夹心法测定标本中人蛋白C（PC）水平。用纯化的抗-PC抗体包被微孔板，制成固相抗体，往包被单抗的微孔中依次加入蛋白C（PC），再与HRP标记的PC抗体结合，形成抗体-抗原-酶标抗体复合物，经过*洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色，并在酸的作用下转化成zui终的黄色。颜色的深浅和样品中的人蛋白C（PC）呈正相关。用酶标仪在450nm波长下测定吸光度（OD值），通过标准曲线计算样品中人蛋白C（PC）浓度。

样本处理及要求：
1. 血清：室温血液自然凝固10-20分钟，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如出现沉淀，应再次离心。
2. 血浆：应根据标本的要求选择EDTA或柠檬酸钠作为抗凝剂，混合10-20分钟后，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应该再次离心。
3. 尿液：用无菌管收集，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应再次离心。胸腹水、脑脊液参照实行。
4. 细胞培养上清：检测分泌性的成份时，用无菌管收集。离心20分钟左右（2000-3000转/分）。仔细收集上清。检测细胞内的成份时，用PBS（PH7.2-7.4）稀释细胞悬液，细胞浓度达到100万/ml左右。通过反复冻融，以使细胞破坏并放出细胞内成份。离心20分钟左右（2000-3000转/分）。仔细收集上清。保存过程中如有沉淀形成，应再次离心。
5. 组织标本：切割标本后，称取重量。加入一定量的PBS，PH7.4。用液氮迅速冷冻保存备用。标本融化后仍然保持2
6. 标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上进行试验，可将标本放于
7. 不能检测含NaN3的样品，因NaN3抑制辣根过氧化物酶的（HRP）活性。
操作步骤
1. 标准品的稀释与加样：在酶标包被板上设标准品孔10孔，在*、第二孔中分别加标准品100μl，然后在*、第二孔中加标准品稀释液50μl，混匀；然后从*孔、第二孔中各取100μl分别加到第三孔和第四孔，再在第三、第四孔分别加标准品稀释液50μl，混匀；然后在第三孔和第四孔中先各取50μl弃掉，再各取50μl分别加到第五、第六孔中，再在第五、第六孔中分别加标准品稀释液50ul，混匀；混匀后从第五、第六孔中各取50μl分别加到第七、第八孔中，再在第七、第八孔中分别加标准品稀释液50μl，混匀后从第七、第八孔中分别取50μl加到第九、第十孔中，再在第九第十孔分别加标准品稀释液50μl，混匀后从第九第十孔中各取50μl弃掉。（稀释后各孔加样量都为50μl，浓度分别为4.8μg/ ml，3.2μg/ ml ，1.6μg/ ml，0.8μg/ ml， 0.4μg/ ml）。
2. 加样：分别设空白孔（空白对照孔不加样品及酶标试剂，其余各步操作相同）、待测样品孔。在酶标包被板上待测样品孔中先加样品稀释液40μl，然后再加待测样品10μl（样品zui终稀释度为5倍）。加样将样品加于酶标板孔底部，尽量不触及孔壁，轻轻晃动混匀。
3. 温育：用封板膜封板后置
4. 配液：将30（48T的20倍）倍浓缩洗涤液用蒸馏水30（48T的20倍）倍稀释后备用。
5. 洗涤：小心揭掉封板膜，弃去液体，甩干，每孔加满洗涤液，静置30秒后弃去，如此重复5次，拍干。
6. 加酶：每孔加入酶标试剂50μl，空白孔除外。
7. 温育：操作同3。
8. 洗涤：操作同5。
9. 显色：每孔先加入显色剂A50μl，再加入显色剂B50μl，轻轻震荡混匀，
10. 终止：每孔加终止液50μl，终止反应（此时蓝色立转黄色）。
11. 测定：以空白空调零，450nm波长依序测量各孔的吸光度（OD值）。 测定应在加终止液后15分钟以内进行。
注意事项：
1． 试剂盒从冷藏环境中取出应在室温平衡15-30分钟后方可使用，酶标包被板开封后如未用完，板条应装入密封袋中保存。
2． 浓洗涤液可能会有结晶析出，稀释时可在水浴中加温助溶，洗涤时不影响结果。
3． 各步加样均应使用加样器，并经常校对其准确性，以避免试验误差。一次加样时间控制在5分钟内，如标本数量多，推荐使用排枪加样。
4． 请每次测定的同时做标准曲线，做复孔。如标本中待测物质含量过高（样本OD值大于标准品孔*孔的OD值），请先用样品稀释液稀释一定倍数（n倍）后再测定，计算时请zui后乘以总稀释倍数（×n×5）。
5． 封板膜只限一次性使用，以避免交叉污染。
6． 底物请避光保存。
7． 严格按照说明书的操作进行，试验结果判定必须以酶标仪读数为准.
8． 所有样品，洗涤液和各种废弃物都应按传染物处理。
9． 本试剂不同批号组分不得混用。

Purpose
This kit allows for the determination of PC concentrations in Human serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Human PC level in the sample，use Purified Human PC antibody to coat microtiter plate wells, make solid-phase antibody, then add PC to wells, Combined PC which With HRP labeled ,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 PC in the samples is then determined by comparing the O.D. of the samples to the standard curve.

6. extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t, specimen can be kept in
7. Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
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 separay. 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 the tenth well, mix , take out 50μl from the ninth and the tenth well discard（add Sample 50μl to each well after Diluting ,（density: 4.8μg/ ml，3.2μg/ ml ，1.6μg/ ml，0.8μg/ ml， 0.4μg/ ml）
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 （or 20-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.
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 mins, 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.
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.
