第二步、明确编码该蛋白的基因与其它哪些物种同源性最好
第三步、寻找检测这些物种蛋白的试剂盒
第四步、咨询商家ELISA是试剂盒使用的抗体类型:多抗还是单抗? 单抗是针对什么抗原决定簇的?
第五步、 做出自己的判断该买哪个试剂盒,或者实在没有可以找公司进行订制实验
Elisa生物试验是一种敏感性高,特异性强,重复性好的实验诊断方法。
但是在选择的时候,也需要注意其他的一些问题。
1、采用何种原料和抗体,是否高效、灵敏、特异
2、规范包被操作,吸附是否均匀
3、重复性、可靠性
6、是否提供技术服务
7、适用于血浆、血清、组织匀浆液、细胞培养上清液、尿液等多种类型的样本
8、可检测动物类型是否丰富
9、可检测指标是否齐全

使用方法:
1、 血清:操作过程中避免任何细胞刺激。使用不含热原和内毒素的试管。收集血液后,1000×g离心10分钟将血红细胞迅速小心地分离。
2、 血浆:EDTA、柠檬酸盐、肝素血浆可用于检测。1000×g离心30分钟去除颗粒。
3、 细胞上清液:1000×g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。1000×g离心10分钟,取上清液。
5、 保存:如果样品不立即使用,应将其分成小部分-70℃保存,避免反复冷冻。尽可能的不要使用溶血或高血脂血。如果血清中大量颗粒,检测前先离心或过滤。不要在37℃或更高的温度加热解冻。应在室温下解冻并确保样品均匀地充分解冻。
的试剂:免疫吸附剂、结合物和酶的底物。
完整的ELISA试剂盒包含以下各组分:
(1)已包被抗原或抗体的固相载体(免疫吸附剂);
(2)酶标记的抗原或抗体(结合物);
(3)酶的底物;
(4)阴性对照品和阳性对照品(定性测定中),参考标准品和控制血清(定量测定
中);
(5)结合物及标本的稀释液;
(6)洗涤液;
(7)酶反应终止液。
