The Rb (Ab-780) antibody is a monoclonal antibody specifically designed to target the retinoblastoma protein (pRb), a critical tumor suppressor involved in cell cycle regulation. The retinoblastoma protein, encoded by the RB1 gene, functions by binding to E2F transcription factors, thereby inhibiting cell cycle progression from the G1 phase to the S phase. Dysregulation or mutation of pRb is strongly associated with various cancers, particularly retinoblastoma, as well as osteosarcomas, bladder cancers, and small cell lung carcinomas.
The Ab-780 clone recognizes an epitope within the C-terminal region of human pRb, making it suitable for detecting both phosphorylated and unphosphorylated forms of the protein across applications such as Western blotting, immunohistochemistry (IHC), and immunoprecipitation (IP). Its specificity has been validated in multiple studies, particularly in research focusing on cell cycle mechanisms, cancer biology, and therapeutic target validation.
Developed in murine hosts, this antibody has become a reliable tool for investigating pRb's role in cellular senescence, apoptosis, and differentiation. Researchers frequently use Rb (Ab-780) to analyze tissue samples or cell lines to assess pRb expression levels, phosphorylation status, and interactions with viral oncoproteins like E7 from HPV, which disrupt pRb function. Its consistent performance and broad compatibility contribute to its widespread use in both basic and translational cancer research.
