Integrin beta-4 (UniProt: P16144; also known as GP150, CD104) is encoded by the ITGB4 gene (Gene ID: 3691) in human. Integrins are heterodimeric cell surface receptors composed of a variable -subunit and a conserved β-subunit. The exact combination of various - and β-subunits dictates the binding specificity of integrins to different ECM components. Integrins are not constitutively active. Activation of an integrin from low ligand-binding affinity state to high ligand-binding affinity state requires conformational change that can originate from either from their cytoplasmic or extracellular interactions. The recognition site for most integrins that bind the ECM consists of an RGD (arginine-glycine-aspartic acid) sequence. Integrins bind to their ligands with low affinity and this binding occurs only when a certain minimum number of integrins are present at specific points known as focal contacts. Integrin β4, primarily expressed by epithelia, is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-27), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 28-710), a transmembrane domain (aa 711-733), and a cytoplasmic domain (aa 734-1822). It contains four fibronectin type III domains. It undergoes palmitoylation by DHHC3 at several cysteines of the membrane-proximal region that enhances its stability and surface expression. Palmitoylation also promotes its secondary association with tetraspanins. It heterodimerizes with 6 and the heterodimer serves as a receptor for laminin and plays a critical structural role in the hemidesmosome of epithelial cells. The 6β4 heterodimer is also involved in tumorigenesis and invasiveness of many cancers and has a pro-metastatic role. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit 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.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

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.
