Description

VAV3 functions as a guanine nucleotide exchange factor that plays a central role in signal transduction pathways, particularly those governing cytoskeletal reorganization, cell migration, and immune cell activation. As a member of the VAV family of oncogenes, VAV3 has garnered significant research interest for its involvement in cancer progression and metastasis, making it a valuable target for investigators studying both fundamental signaling mechanisms and disease-relevant pathways.

This recombinant monoclonal antibody, clone 24B11, offers the consistency and reliability that demanding experimental workflows require. Developed using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The rabbit IgG format, raised against a synthesized peptide from human VAV3 protein, has been affinity-purified to ensure high specificity for your target.

Validation studies demonstrate robust performance in flow cytometry applications, with recommended dilutions ranging from 1:50 to 1:200. Testing in U87 glioblastoma cells using intracellular staining protocols confirmed clear signal separation from isotype controls, with cells fixed in formaldehyde and permeabilized with Triton X-100 prior to antibody incubation. This validated workflow provides a reliable starting point for researchers investigating VAV3 expression in human cell populations.

The unconjugated format provides flexibility for pairing with your preferred secondary detection systems, while the glycerol-containing buffer ensures stability during storage. Whether you are characterizing VAV3 expression patterns in cancer cell lines or investigating its role in signal transduction cascades, this antibody delivers the reproducible performance essential for generating publication-quality data.

Target Background

Function

Exchange factor for GTP-binding proteins RhoA, RhoG and, to a lesser extent, Rac1. Binds physically to the nucleotide-free states of those 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. May be important for integrin-mediated signaling, at least in some cell types. In osteoclasts, along with SYK tyrosine kinase, required for signaling through integrin alpha-v/beta-1 (ITAGV-ITGB1), a crucial event for osteoclast proper cytoskeleton organization and function. This signaling pathway involves RAC1, but not RHO, activation. Necessary for proper wound healing. In the course of wound healing, required for the phagocytotic cup formation preceding macrophage phagocytosis of apoptotic neutrophils. Responsible for integrin beta-2 (ITGB2)-mediated macrophage adhesion and, to a lesser extent, contributes to beta-3 (ITGB3)-mediated adhesion. Does not affect integrin beta-1 (ITGB1)-mediated adhesion.
