| Storage and Stability: | 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. |
| Target description: | Integrin alpha-M (UniProt: P11215; also known as CD11 antigen-like family member B, CR-3 alpha chain, Cell surface glycoprotein MAC-1 subunit alpha, Leukocyte adhesion receptor MO1, Neutrophil adherence receptor, CD11b) is encoded by the ITGAM (also known as CD11B, CR3A) gene (Gene ID: 3684) in human. Integrins are a/b heterodimeric adhesion receptors that couple the extracellular matrix on other cells with the contractile cytoskeleton to transduce mechanochemical signals across the plasma membrane. CD11b is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-16), which is subsequently cleaved off to generate the mature form that that contains a long extracellular domain (aa 17-1104), a transmembrane domain (aa 1105-1128), and a short cytoplasmic domain (aa 1129-1152). It is predominantly expressed in monocytes and granulocytes. It is usually found as a heterodimer of a/b subunits and associates with Integrin b2 (ITGB2). CD11b/Integrin b2 has been implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement-coated particles and pathogens. The major ligand recognition site of CD11b/integrin b2 has been mapped to the A-domain in the CD11b subunit (CD11bA). CD11b/integrin b2 also serves as a receptor for fibrinogen, factor X and ICAM1. It recognizes P1 and P2 peptides of fibrinogen gamma chain. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. |
