Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human STAP2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
STAP2 (signal-transducing adaptor protein 2, BRK substrate, BKS) is an adaptor protein expressed in various tissues and cell lines (1). The protein sequence of STAP2 contains a PH domain, an SH2 like domain, a proline rich region, and a YXXQ motif for interaction with various signaling molecules. (2). In the immune system, STAP2 plays important roles in cytokine signaling, macrophage activation, T cell migration, and motility via interaction with, and regulation of, signaling molecules such as STAT3, STAT5, IKKα/β, CSF1R, VAV, FAK, and Fas ligand. In leukemia, prostate cancer, breast cancer, and melanoma, STAP2 has been shown to promote tumor growth and metastasis via stabilization and activation of signaling molecules, including BCR/ABL, EGFR, BRK, STATs, and tyrosinase (3-6).
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
