The RB Antibody (CAB16966) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, produced in rabbits, exhibits high specificity and sensitivity when detecting RB1 in human samples, making it a reliable choice for Western blot applications.RB1 is a tumor suppressor protein that plays a crucial role in cell division and growth control. Mutations in the RB1 gene have been linked to various cancers, including retinoblastoma, osteosarcoma, and breast cancer. By targeting RB1 with this polyclonal antibody, researchers can accurately monitor RB1 expression levels in different cell types, providing valuable insights into cell cycle regulation and cancer progression.
This antibody is validated for use in WB, IF/ICC, ELISA applications and has demonstrated reactivity against Human samples.

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.
