DAS-ELISA试剂盒中抗体有包被抗体和酶标抗体,这两种抗体是一种抗体,前者没有酶标,后者用酶进行了标记。
NCM-ELISA一般有一抗和二抗,这两种抗体不一样,前者(一抗)一般是鼠抗体或兔抗体,没有酶标,相对应的二抗一般是羊抗鼠或羊抗兔抗体,用酶进行标记。也有用马大规模备抗体的。
TDS-ELISA是三抗体ELISA,第三级的抗体是将信号级联放大。
以上三种是比较常见的,还有其他一些试剂盒,可参考免疫学的内容。
首先要什么有什么的,你得好好考虑一下。
2、看生产地址
根本没有生产地址,我们知道做实验做产品需要很多的仪器、试剂、耗材,没有人相信一间简单的屋子可以生产各种样的试剂盒。
3、看产品包装
没有任何的生产地址、联系方式等信息,这种产品有问题了连个投诉的地方都没有。
4、看公司网站
有些打着国外原装旗号,整个公司网站为英文页面,实际注册IP地址在中国。如果写着国外的地址,让你国外的朋友实地去看一下!
5、做交叉验证
拿对方提供的几个种类的试剂盒,把里面的关键组份相互替换做做实验,如果交叉严重,只能说明是一种原料生产的试剂盒贴了不同的标签。
6、看价格
价格低得离谱,却打着进口大公司原料分装,核算成本,这种低得离谱的价格是连原料都买不起的。
