Binding Specificity: AA 514-610, underphosphorylated

Brand: BD Pharmingen™

Cross-Reactivity: Mouse (Murine)

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Sodium azide is a reversible inhibitor of oxidative metabolism, therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

Purification: The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Immunogen: Recombinant full-length human Rb

Isotype: IgG1

Application Details

Application Notes: Applications include immunoprecipitation at 1-2 µg/one million cells. Rb migrates as multiple, closely-spaced bands between approximately 110-116 kDa when sized on denaturing polyacrylamide gels (i.e. by SDS/PAGE). The multiple bands represent different Rb phosphorylation states, the higher molecular weight bands are more highly phosphorylated than the lower molecular weight bands. The level of phosphorylation is cell cycle dependent, and may also be cell type dependent (not all forms are seen in all cell types that express Rb). Gel conditions influence the actual number of bands observed. In cases where optimal band separation is desired, use a 7 to 10% non-gradient long (at least 12 inches) gel. MOLT-4 human leukemia cells (ATCC CRL-1582) are suggested as a positive control.

Target Details for Retinoblastoma 1

Target: Retinoblastoma 1 (RB1)

Alternative Name: Rb

Background: The retinoblastoma gene encodes a nuclear phosphoprotein (Rb or p110Rb) which is expressed in most normal cells of vertebrates and acts as a tumor suppressor gene product. An underphosphorylated form of Rb is mainly found in resting or fully differentiated cells, whereas the hyperphosphorylated form is present in proliferating cells. Only the underphosphorylated form of Rb binds specifically to viral oncogenes such as SV40 large T, adenoviral EIA and HPV-E7. This interaction may partially contribute to the transforming activity of these viral oncoproteins. Rb also interacts with several cyclins including A, D, and E as well as the transcriptional activator E2F. The importance of these interactions for the biological function of Rb is still being elucidated. G99-549 recognizes only the fast migrating, underphosphorylated form of Rb protein. G99-549 cross-reacts with mouse underphosphorylated Rb. The epitope has been mapped to amino acids 514-610 (box A) of human Rb. Recombinant full-length human Rb was produced in the baculovirus expression vector system (BEVS), purified and used as immunogen.
