ANTI-INTEGRIN BETA1 ANTIBODY CLONE 8E3

General description

Integrin beta1 is a transmembrane glycoprotein that forms noncovalent complexes with various alpha integrin subunits to form the functional receptors that bind to specific extracellular matrix proteins. Integrin receptors are involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metatastatic diffusion of tumor cells. Interactions between integrins and extracellular matrix lead to activation of signal transduction pathways and regulation of gene expression. Phosphorylation of threonines 788 and 789 on integrin beta1 receptor may play a key role in cell-cycle dependent regulation.

Specificity

This antibody recognizes the N-terminus of the PSI domain of Integrin Beta1. Under native conditions, clone 8E3 is shown to recognize the unbent, monomeric ER form of Integrin Beta1 at the PSI domain; however, the epitope only becomes exposed in the Golgi form after denaturation. This observation suggests that the epitopes are present in monomeric beta 1-integrins, but become lost following assembly with alpha-integrin subunits (Tiwari, S., et al. (2011). J Cell Sci. 124(10):1672-1680.; Mould, A. P., et al. (2004). J Biol Chem. 280(56):4238-4226.)

This Anti-Integrin beta1 Antibody is validated for use in WB, IP & activity assays for the detection of Integrin beta1.

Western Blot Analysis: A 1:100,000 dilution from a representative lot detected Integrin protein in WB under non-reducing conditions.

Activity Assay Analysis: A representative lot from an independent laboratory stimulated cellular adhesion and increased ligand binding activity of Integrin Beta1 (Mould, A. P., et al. (2004). J Biol Chem. 280(56):4238-4226.).

Immunoprecipitation Analysis: A representative lot from an independent laboratory immunoprecipitated Integrin Beta1 in IP (Tiwari, S., et al. (2011). J Cell Sci. 124(10):1672-1680.).

Quality

Evaluated by Western Blot in HT-1080 cell lysate.

Western Blot Analysis: A 1:2,000 dilution of this antibody detected Integrin Beta1 in 10 µg of HT-1080 cell lysate.

Target description

~100-150 kDa observed. The calculated molecular weight is 86 kDa; however, it is known to have multiple isoforms that range between ~87-91 kDa This protein is highly glycosolated and depending on the cell line or tissue, it has been observed at ~100-150 kDa (Bridger, P. S., et al. (2008). Biol Reprod. 79(2):274-282.).

Physical form
