The pRB ELISA kits listed below are analytical tools for measuring concentrations of pRB in various samples. pRB is an alternative name for the human RB1 gene, which encodes the protein, RB transcriptional corepressor 1. It has been mentioned that pRB plays a role in cell differentiation and cell division, among other functions. Structurally, 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.
