人丙型肝炎 E 蛋白(HCVE)酶联免疫分析（ELISA）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
液体样本中丙型肝炎 E 蛋白(HCVE)含量。
实验原理：
本试剂盒应用双抗体夹心法测定标本中人丙型肝炎 E 蛋白(HCVE)水平。用纯化的人丙
型肝炎 E 蛋白(HCVE)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丙型
肝炎 E 蛋白(HCVE)，再与 HRP 标记的丙型肝炎 E 蛋白(HCVE)抗体结合，形成抗体-抗原-
酶标抗体复合物，经过彻底洗涤后加底物 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最终的黄色。颜色的深浅和样品中的丙型肝炎 E 蛋白(HCVE)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丙型肝炎
E 蛋白(HCVE)浓度。

人丙型肝炎 E 蛋白(HCVE)酶联免疫分析（ELISA）试剂盒操作步骤
1. 标准品的稀释与加样：在酶标包被板上设标准品孔 10 孔，在第一、第二孔中分别加标
准品100μl，然后在第一、第二孔中加标准品稀释液 50μl，混匀；然后从第一孔、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 90pg/ml，60pg/ml ，30pg/ml，15pg/ml，7.5pg/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
品最终稀释度为 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 37℃温育 30分钟。
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，37℃避光显色
15分钟.
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
大于标准品孔第一孔的 OD 值），请先用样品稀释液稀释一定倍数（n 倍）后再测定，计
算时请最后乘以总稀释倍数（×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。3
9．本试剂不同批号组分不得混用。
10. 如与英文说明书有异，以英文说明书为准。
计算：
以标准物的浓度为横坐标，OD值为纵坐标，
在坐标纸上绘出标准曲线，根据样品的 OD
值由标准曲线查出相应的浓度；再乘以稀释
倍数；或用标准物的浓度与 OD 值计算出标
准曲线的直线回归方程式，将样品的 OD 值
代入方程式，计算出样品浓度，再乘以稀释
倍数，即为样品的实际浓度。

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
the tenth well, mix , take out 50µl from the ninth and the tenth well discard(add Sample 50µl to
each well after Diluting ,(density: 90pg/ml，60pg/ml ，30pg/ml，15pg/ml，7.5pg/ml)
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.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30 min at 37℃.
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 the7
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.
9. Do not mix reagents with those from other lots.8
