| Function | The retinoblastoma protein (protein name abbreviated Rb; gene name abbreviated Rb, RB or RB1) is a tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, pRb is phosphorylated, inactivating it, and the cell cycle is allowed to progress. It is also a recruiter of several chromatin remodeling enzymes such as methylases and acetylases. pRb belongs to the pocket protein family, whose members have a pocket for the functional binding of other proteins. Should an oncogenic protein, such as those produced by cells infected by high-risk types of human papillomavirus, bind and inactivate pRb, this can lead to cancer. The RB gene may have been responsible for the evolution of multicellularity in several lineages of life including animals. |

WB
Western blot analysis of Phospho-Rb (S795) on different lysates with Rabbit anti-Phospho-Rb (S795) antibody at 1/2,000 dilution. Lane 1: HeLa cell lysate, Lane 2: HeLa treated with 100ng/mL Nocodazole for 18 hours cell lysate, Lane 3: U-2 OS cell lysate, Lane 4: U-2 OS treated with 50ng/mL Nocodazole for 8 hours cell lysate, Lysates/proteins at 20 µg/Lane. Exposure time: Lane 1-4 (left): 40 seconds; Lane 1-4 (right): 1 minute; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
ICC/IF
Immunocytochemistry analysis of HeLa cells treated with 100ng/mL Nocodazole for 18 hours labeling Phospho-Rb (S795) with Rabbit anti-Phospho-Rb (S795) antibody at 1/500 dilution. Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Phospho-Rb (S795) antibody at 1/500 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.| Application Notes | WB:1:2000 ICC:1:500 |
