The protein encoded by RB1（RB transcriptional corepressor 1） is a negative regulator of the cell cycle and was the first tumor suppressor gene found. The encoded protein also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in RB1 are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma.蛋白别名为：RB1; Retinoblastoma-associated protein; p105-Rb; pRb; Rb; pp110;基因ID为：5925；蛋白质ID:P06400
应用类型
IHC-p，IF，ELISA补充：最优的抗体稀释比例需要基于客户实验进行优化.建议的起始稀释比例如下: IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:40000. Not yet tested in other applications.
免疫原
