Sequence :

Specificity :Recognizes the VAV protein

Cited Applications :WB, IP

Cross Reactivity :Western blot VAV from human cells

VAV from other species may also be detectable.

Host  :Rabbit

Immunogen :Synthetic peptide corresponding to amino acids 172-176 of human VAV

Purification :Affinity chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For optimal performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data :Representative Immunoprecipitation with 2 μg of Anti-VAV using 500 μg of Jurkat and THP1cell lysates.

Sample Data :Representative Western blot with Anti-VAV (1:1000) using 3 μg, 10 μg and 30 μg of Jurkat cell lysate.

Scientific Background :VAV is a proto-oncogene that is a member of the Dbl family of guanine nucleotide exchange factors (GEF) for the Rho family of GTP binding proteins. VAV plays a vital role in hematopoiesis and in T-cell and B-cell development as well as in their activation. VAV is the specific binding partner of Nef proteins from HIV-1 (1). Co-expression and binding of these VAV partners initiates profound morphological changes, cytoskeletal rearrangements and JNK/SAPK pathway activation leading to increased levels of viral transcription and replication. VAV is also the guanine nucleotide dissociation inhibitor for Ras.
