Intended Use:
The AESQC quality controls are reagents obtained from pools of human sera available with different autoantibodies that allow a multi parametric control in autoimmune disease diagnosis.These controls were developed to help lab managers to ensure that analytical error stays within acceptable limits.
AESQCs are unassayed ready to use reagents which should be handled in the same way as patient samples and can be used for monitoring the performance of ELISA and FARR assays.
Our AESQC controls are formulated to give positive reactions for the respective autoantibody and the lab should establish their own working ranges for each new lot depending from the test system and procedures being used.
AESQC Pool 3 can be used as function controls of AESKUBLOTS® Line Immuno Assays (LIA).
Antibodies:
aCL IgM, aPL IgM, B2GP1 IgG and IgM, DNA (ELISA & FARR)

由于质粒的不兼容性,拥有同种复制子的质粒不能在同一细胞内稳定共存,经过几代的复制,会质粒丢失,所以并不是任何两个或两个以上质粒都可以在同一细胞内稳定存在,但是可以同时进入.
稳定转染的细胞株,就是转染后质粒可以稳定整合到基因组上不会因细胞分裂而丢失。区别于质粒瞬时转染不能长时间保留质粒在细胞里。
推荐了解“主细胞库”“工作细胞库”这两个名词。
先提取RNA,反转录成cDNA,然后根据目的基因设计PCR引物,通过半定量RT-PCR确定目的基因表达.
正因为检测的是mRNA,所以要先反转录成cDNA才能PCR.
1.将外源基因插入慢病毒载体
2.将构建完成的载体与慢病毒包装质粒混合,共转染靶细胞
3.收集病毒液
4.用病毒液感染靶细胞
5.用载体上带的抗生素进行筛选,如果没有,可以用无限稀释法
6.获得稳转株
