Retinoblastoma gene product (RB) is a tumor suppressor protein and acts as cell cycle regulator. Recently, RB has been shown to play a role in apoptosis. During apoptosis, RB is subjected to cleavage by caspase 3 like protease. Caspase 3 cleaves RB into 48 and 68kDa fragments. Cleavage of RB would make it functionally inactive, causing release of E2F 1. The E2F 1 then may promote apoptosis.
WB: Use at a concentration of 2 ?g/ml. Detects a band of approximately 68 kDa (predicted molecular weight: 68 kDa). IHC: (see Liu et al, 2005 in Product Citation). Not tested in other applications. Optimal dilutions/concentrations should be determined by the end user.
