Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxyl terminus of human βIG-H3. Antibodies were purified by peptide affinity chromatography.

Background

βIG-H3 (TGFBI/RGD-CAP/Kerato-epithelin) is a 683-amino acid secretory protein induced by TGF-β that plays a role in cell adhesion, differentiation, and apoptosis (1-4). βIG-H3 contains an internal cysteine-rich EMI domain followed by four fasciclin-1 domains and a carboxy terminal RGD domain (1,2). It contributes to cell adhesion through interactions with integrins as well as a number of extracellular matrix (ECM) proteins including collagen, fibronectin, and laminin (5-7). ECM βIG-H3 is found in a wide variety of tissues (8-12). Mutations in the βIG-H3 gene as well as elevated protein levels are most notably associated with corneal dystrophies (13).

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.
