Description de la cible

Receptor tyrosine-protein kinase erbB-3 (UniProt: P21860; also known as EC:2.7.10.1, Proto-oncogene-like protein c-ErbB-3, Tyrosine kinase-type cell surface receptor HER3) is encoded by the ERBB3 (also known as HER3) gene (Gene ID: 2065) in human. ErbB3 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 20-643), a transmembrane domain (aa 644-664), and a cytoplasmic domain (aa 665-1342). Its extracellular domain is formed of two ligand-binding regions (L1 and L2) and two cysteine-rich regions (CR1 and CR2). In the absence of a ligand, the extracellular domain stayed in a locked conformation and is stabilized by interactions between CR1 and CR2 regions that prevents its dimerization. Its tyrosine kinase domain is localized to amino acids 709-966 and shares homology with EGFR and ErbB2 kinase domain. However, the tyrosine kinase activity is impaired due to modified residues and its activation requires the formation of heterodimers with other EGFR family receptors. Known ligands for ErbB3 include neuregulins (NRG) and NRG1 and NRG2 appear to be the most active. Downstream signaling pathways activated include MAPK and PI3 Kinase pathways. ErbB3 has been implicated in cell division and survival and its expression is essential for cell proliferation in several tumor models and transformation of normal tissues. It has also been implicated in acquired resistance to EGFR-tyrosine kinase inhibitors. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

Reconstitution

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.

Stockage et stabilité

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.
