Rb (phospho Thr821) rabbit pAb from ELK Biotechnology Read more ›
Rb (phospho Thr821) rabbit pAb is a research-use antibody from ELK Biotechnology for studying Rb in IHC, IF, ELISA workflows with listed reactivity for Human, Mouse, Rat. Specifications and supporting documents below should be reviewed when planning the experiment.
The protein encoded by this gene 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 this gene are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma. [provided by RefSeq, Jul 2008],
