pRb2 p130 Antibody (600-401-B11) in WB
Western blot using Rocklands affinity purified anti-Spa310 antibody shows detection of endogenous pRb2/p130 protein in whole LNCaP cell extracts. The band at ~130 kDa, indicated by the arrowhead, corresponds to the expected molecular weight of pRb2/p130. The membrane was blocked overnight with a milk buffer at 4° C. Primary antibody was diluted 1:500 and reacted with the membrane overnight at 4° C. ECL was used for detection.

Product Specific Information
Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
This antiserum is directed against Spa310 and reacts with the Spa310 domain of pRb2/p130 from human tissues. Based on the sequence we expect this antibody to react as well Spa310 from chimpanzee and orangutan, and with lesser affinity, Spa310 from horse, dog, bovine, rat and opossum.
Target Information
RBL2 (also known as p130) or Retinoblastoma-like protein 2 is a key regulator of entry into cell division. It is directly involved in heterochromatin formation by maintaining overall chromatin structure and (in particular) that of constitutive heterochromatin by stabilizing histone methylation. RBL2 recruits and targets histone methyltransferases KMT5B and KMT5C leading to epigenetic transcriptional repression. It controls histone H4 'Lys20' trimethylation. It probably also acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. RBL2 serves as a potent inhibitor of E2F-mediated trans-activation and associates preferentially with E2F5.
