Anti-ITGA3 Antibody, clone P1B5 ZooMAb^® Mouse Monoclonal

Integrin alpha-3 (UniProt: P26006; also known as CD49 antigen-like family member C, FRP-2, Galactoprotein B3, GAPB3, VLA-3 subunit alpha, CD49c) is encoded by the ITGA3  (also known as MSK18) gene (Gene ID: 3675) in human. Integrins are heterodimeric integral membrane proteins composed of an α subunit and 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.  The structural and functional diversity of the integrin family is based upon the pairing abilities of the individual α and β subunits. Integrin α3 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-32), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 33-991), a transmembrane domain (aa 992-1014), and a cytoplasmic domain (aa 1015-1051). It has two chains- a heavy chain (aa 33-872) and a light chain (aa 876-1051).  Integrin α3 dimerizes with integrin β1 to form a receptor for fibronectin, laminin, collagen, epiligrin, thrombospondin, and chondroitin sulfate proteoglycan 4 (CSPG4). It provides a docking site for FAP (seprase) at invadopodia plasma membranes in a collagen-dependent manner and hence may participate in the adhesion, formation of invadopodia and matrix degradation processes, promoting cell invasion. Overexpression of ITGA3 has been reported in intrahepatic cholangiocarcinoma. It promotes proliferation and cell cycle progression leading to poor prognosis. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Clone P1B5 is a ZooMAb^® mouse recombinant monoclonal antibody that detects Integrin 3 (ITGA3). It targets an epitope within the extracellular domain.

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.

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.
