General description
Integrin beta-1 (UniProt: P05556; also known as Fibronectin receptor subunit beta, Glycoprotein IIa, GPIIA, VLA-4 subunit beta, CD29) is encoded by the ITGB1 (also known as FNRB, MDF2, MSK12) gene (Gene ID: 3688) in human. Integrins are heterodimeric integral membrane proteins composed of a variable α-subunit and a conserved β-subunit that function in cell surface adhesion and signaling. They contain a large extracellular domain responsible for ligand binding, a single transmembrane domain, and a cytoplasmic domain. The exact combination of various α and β-subunits dictates the binding specificity of integrins to different ECM components. Although both subunits are required for adhesion, the binding specificity primarily depends on the extracellular portion of the α-subunit. Integrin β1 is a single-pass type I membrane glycoprotein that associates with one of the a subunits to form receptor for fibronectin. It recognizes the sequence R-G-D in a wide array of ligands. Five isoforms of integrin β1 have been described that are produced by alternative splicing. Integrin β1 is synthesized with a signal peptide (aa 1-20) that is subsequently cleaved off. The mature form has an extracellular domain (aa 21-728), a helical domain (aa 729-751) and a cytoplasmic region (aa 752-798). Isoform 1 of integrin β1 is widely expressed and other isoforms are generally co-expressed with a more restricted distribution. Isoform 2 is expressed in skin, liver, skeletal muscle, cardiac muscle, placenta, umbilical vein endothelial cells, neuroblastoma cells, lymphoma cells, hepatoma cells and astrocytoma cells. Isoform 3 and isoform 4 are expressed in muscle, kidney, liver, placenta, cervical epithelium, umbilical vein endothelial cells, fibroblast cells, embryonal kidney cells, platelets, and several blood cell lines. Isoform 4 is selectively expressed in peripheral T-cells and isoform 5 is expressed specifically in striated muscle (skeletal and cardiac muscle). Isoform 2 is reported to interfere with isoform 1 resulting in a dominant negative effect on cell adhesion and migration (in vitro). (Ref.: Balcaz, A., et al. (1993). J. Cell Biol. 121(1); 171-178; Altruda, F., et al. (1990). Gene. 95(2); 261-266).

Biochem/physiol Actions
Clone P4C10 is a ZooMAb® mouse recombinant monoclonal antibody that specifically detects Integrin β1/CD29. It targets an epitope within 12 amino acids from the extracellular domain.
Physical form
Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
Other Notes
Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
