Western Blot (WB)

(Western blot analysis of RB1 Antibody (C-term) in 293 cell line lysates (35ug/lane). RB1 (arrow) was detected using the purified Pab. (2ug/ml))

Immunohistochemistry (IHC)

(Formalin-fixed and paraffin-embedded human testis tissue reacted with RB1 Antibody (C-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.)

Flow Cytometry (FC/FACS)

(RB1 Antibody (C-term) flow cytometric analysis of 293 cells (bottom histogram) compared to a negative control cell (top histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.)

Uniprot Description

Rb: retinoblastoma tumor suppressor protein regulates cell proliferation by controlling progression through the G1-phase restriction point. Has three distinct binding domains and interacts with regulatory proteins including the E2F family of transcription factors, c-Abl tyrosine kinase and proteins with a conserved LXCXE motif. Cell cycle-dependent phosphorylation by Cdks inhibits Rb target binding, thus allowing cell cycle progression. Recruits and targets histone methyltransferase suv39h1 leading to epigenetic transcriptional repression.
