Integrin beta-1 (UniProt P05556; also known as CD29, Glycoprotein Iia, GPIIA, Integrin VLA-4 subunit beta, Very late activation protein, beta polypeptide) is encoded by the ITGB1 (also known as FNRB, MDF2, MSK12, VLA-BETA, VLAB) gene (Gene ID 3688) in human. Integrin beta-1 is a 130 kDa transmembrane glycoprotein that interact with various integrin alpha subunits (including alpha 1, alpha 2, alpha 3, alpha 4, alpha 5, and alpha 6) to form the functional receptor complexes that bind to specific extracellular matrix proteins. Integrin receptors regulate a variety of important biological functions, including embryonic development, wound repair, hemostasis, and prevention of programmed cell death. They are also implicated in abnormal pathological states such as tumor directed angiogenesis, tumor growth and metastasis. These heterodimeric receptors bridge the cytoplasmic actin cytoskeleton with proteins present in the extracellular matrix and/or on adjacent cells. Interactions between integrins and the extracellular matrix lead to the activation of signal transduction pathways and regulation of gene expression.

Anti-Integrin β1 Antibody, clone MB1.2 is an antibody against Integrin β1 for use in FC, IH, IP & WB.
A previous lot of this anitbody was used to immunoprecipitate VLA (β1) integrins from lysate of 106 cell equivalent: 2 μg.
A 10 μg/mL concentration of a previous lot was used in FC.
Immunohistochemistry in frozen tissue sections:
20 μg/mL from a previous lot was used. As a result of the wide tissue distribution of VLA (β1), binding of MAB1997 to diverse cell types is commonly observed.
Does not block VLA integrin mediated cell adhesion to matrix proteins. Activation of VLA (β1) integrin signaling properties by MAB1997 has not been characterized.
10 µg/mL. Effective for samples that have been SDS-denatured and heated. Not effective for reduced samples.
Optimal working dilutions must be determined by end user.
Routinely evaluated by Western Blot on C2C12 lysate.
Western Blot Analysis:
1:1000 dilution of this lot detected integrin β1 on 10 μg of C2C12 lysate.
~88 kDa (non-glycosylated) and ~130 kDa ( glycosylated).
Purified rat monoclonal IgG2κ liquid in buffer containing 0.02 M phosphate buffer, pH 7.6, 0.25 M NaCl with 0.1% NaN3
Human OVCAR5 cell line whole cell lysate
Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
