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.蛋白別名為：RB1; Retinoblastoma-associated protein; p105-Rb; pRb; Rb; pp110;基因ID為：5925；蛋白質ID:P06400
應用類型
WB，IHC-p，ELISA補充：最優的抗體稀釋比例需要基于客戶實驗進行優化.建議的起始稀釋比例如下: WB: 1:500-1:2000, IHC-p: 1:100-1:300, ELISA: 1:40000. Not yet tested in other applications.
免疫原
