These p105-Rb ELISA kits are immunodetection tools for measuring the levels of p105-Rb in biological samples. p105-Rb is an alias of the human RB1 gene, which encodes the protein, RB transcriptional corepressor 1. Notably, p105-Rb is known to play a role in cell differentiation and cell division, among other functions. The RB1 protein is described to be 928 amino acid residues in length and 106.2 kilodaltons in mass. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be expressed in the retina. This protein is known to be methylated, acetylated and phosphorylated. Other names for this target antigen include OSRC, PPP1R130, and RB. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
