实验概要The peptide competition assay/blocking procedure can be used in western blotting, IHC and ELISA. The peptide competition assay (PCA) is a recommended procedure for confirming the specific band reactivity of an antibody, especially domain specific antibodies like phospho-specific antibodies. It is not uncommon to see more than one band on immunoblots of lysates when probing with a primary antibody. The......阅读全文

IRES－与－2A－peptide在同时表达多个目标基因中的应用比较
导读Hello! 大家好！有一个问题不知道大家考虑过没有：为了研究单个基因的功能机制或实现多基因协同表达, 那这种同时表达多个目标基因该如何实现呢？实际上，目前广泛采用多顺反子表达方案,即利用内部核糖体进入位点(internal ribosome entry site,IRES)或自剪切多肽2A(s
