Sizes: 50µl, 100µl

Catalogue Numbers: BS67100-50, BS67100-100

Product: Liquid in 0.42% Potassium phosphate, 0.87% Sodium chloride, pH 7.3, 30% glycerol, and 0.01% sodium azide.

Swiss-Prot: P52735

Host: Rabbit

Reactivity: Human

Applications: WB, IHC, IF/ICC

All Applications: WB (1/500 - 1/1000), IH (1/100 - 1/200), IF/IC (1/100 - 1/500)

Background: Guanine nucleotide exchange factor for the Rho family of Ras-related GTPases. Plays an important role in angiogenesis. Its recruitment by phosphorylated EPHA2 is critical for EFNA1-induced RAC1 GTPase activation and vascular endothelial cell migration and assembly (By similarity).

Purification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).

Storage and Stability: Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.

Specificity: Recognizes endogenous levels of VAV2 (pY142) protein.

Bioworld Molecular Weight: ~ 100 kDa

Note: For research use only, not for use in diagnostic procedure.

Extra Notes: Western blot analysis of VAV2 (pY142) expression in A431 TNF-treated (A), HEK293T (B) whole cell lysates., Immunohistochemical analysis of VAV2 (pY142) staining in human breast cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX., Immunofluorescent analysis of VAV2 (pY142) staining in A431 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a hidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark. DAPI was used to stain the cell nuclei (blue).

Alternative Name: Guanine nucleotide exchange factor VAV2; VAV-2

Immunogen: KLH-conjugated synthetic peptide encompassing a sequence within the N-term region of human VAV2. The exact sequence is proprietary.
