人甲胎蛋白异质体 3（AFP-L3）ELISA 检测试剂盒
使用说明书
检测原理
试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被人甲胎蛋白异质体3（AFP-L3）捕获抗体的包被微孔中，依次加入 标本、标准品、HRP标记的检测抗体，经过温育并彻底洗涤。用底物TMB显色，TMB在过氧化物酶的催化下转化成蓝色，并在酸的作用下 转化成*终的黄色。颜色的深浅和样品中的人甲胎蛋白异质体3
（AFP-L3）呈正相关。用酶标仪在450nm 波长下测定吸光度（OD 值），计算样品浓度。
样品收集、处理及保存方法
1. 血清：使用不含热原和内毒素的试管，操作过程中避免任何细胞刺激，收集血液后，3000 转离心 10 分钟将血清和红细胞迅速小心地分离。
2. 血浆：EDTA、柠檬酸盐或肝素抗凝。3000 转离心 30 分钟取上清。
3. 细胞上清液：3000 转离心 10 分钟去除颗粒和聚合物。
4. 组织匀浆：将组织加入适量生理盐水捣碎。3000 转离心 10 分钟取上清。
5. 保存：如果样本收集后不及时检测，请按一次用量分装，冻存于
-20℃，避免反复冻融，在室温下解冻并确保样品均匀地充分解冻。
自备物品
1.酶标仪（450nm）
2.高精度加样器及枪头：0.5-10uL、2-20uL、20-200uL、200-1000uL
3.37℃恒温箱
Note:The samples shoule be centrifugated dequately ａnd no hemolysis or granule was allowed.
Materials required but not supplied
1. Standard microplate reader(450nm)
2. Precision pipettes ａnd Disposable pipette tips.
3. 37 ℃ incubator
Precautions
1. Do not substitute reagents from one kit to another. Standard, conjugate and microplates are matched for optimal performance. Use only the reagents supplied by manufacturer.
2. Do not remove microplate from the storage bag until needed. Unused strips
should be stored at 2-8°C in their pouch with the desiccant provided.
3. Mix all reagents before using.
Remove all kit reagents from refrigerator and allow them to reach room temperature ( 20-25°C)

Reagent preparation
20×wash solution:Dilute with Distilled or deionized water 1:20.
Assay procedure
1. Prepare all r eagen t s before starting assay procedure. It is recommended that all Standards ａnd Samples be added in duplicate to the Microelisa Stripplate.
2. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.
3. Add Sample: Add testing sample 10μl Then add sample diluent 40μl to testing sample well; Blank well doesn’t add anyting.
4. Add 100μl of HRP-conjugate reagent to each well, cover with an adhesive strip and incubate for 60 minutes at 37°C.
5. Aspirate each well ａnd wash, repeating the process four times for a total of five washes. Wash by filling each well with Wash Solution (400μl) using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate ａnd blot it against clean paper towels.
6. Add chromogen solution A 50μl ａnd chromogen solution B 50μl to each well.
Gently mix ａnd incubate for 15 minutes at 37°C. Protect from light.
7. Add 50μl Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not appear uniform, gently tap the plate to ensure thorough mixing.
