Vav Isoform Antibody Sampler Kit #5145
This product is discontinued
The Vav Isoform Antibody Sampler Kit is an economical way to examine the total protein levels of Vav isoforms 1, 2, and 3. The kit includes enough primary and secondary antibodies to perform four Western blot experiments.
Each antibody in the Vav Isoform Antibody Sampler Kit detects endogenous levels of the specified Vav isoform.
Polyclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the central sequence of human Vav3. Antibodies are purified by protein A and peptide affinity chromatography. Monoclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues in the carboxy terminus of Vav1 and near the carboxy terminus of human Vav2.
Vav proteins belong to the Dbl family of guanine nucleotide exchange factors (GEFs) for Rho/Rac small GTPases. The three identified mammalian Vav proteins (Vav1, Vav2 and Vav3) differ in their expression. Vav1 is expressed only in hematopoietic cells and is involved in the formation of the immune synapse. Vav2 and Vav3 are more ubiquitously expressed. Vav proteins contain the Dbl homology domain, which confers GEF activity, as well as protein interaction domains that allow them to function in pathways regulating actin cytoskeleton organization (reviewed in 1). Phosphorylation stimulates the GEF activity of Vav protein towards Rho/Rac (2,3).
