ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 1B13 is a Rabbit recombinant monoclonal antibody that specifically detects Receptor tyrosine-protein kinase erbB-2 (ErbB2/HER-2). It targets an epitope within 24 amino acids from the C-terminal region.

KLH-conjugated linear peptide corresponding to 24 amino acids from the C-terminal region of human Receptor tyrosine-protein kinase erbB-2 (ErbB2/HER-2).

Anti-ErbB2/HER-2, clone 1B13 ZooMAb^®, Cat. No. ZRB1245, is a recombinant Rabbit monoclonal antibody that targets ErbB2/HER-2 and is tested in Affinity Binding Assay, Flow Cytometry, Immunocytochemistry, Immunohistochemistry, and Western Blotting.

Receptor tyrosine-protein kinase erbB-2 (UniProt: P04626; also known as EC:2.7.10.1, Metastatic lymph node gene 19 protein, MLN 19, Proto-oncogene Neu, Proto-oncogene c-ErbB-2, Tyrosine kinase-type cell surface receptor HER2, p185erbB2, CD340) is encoded by the ERBB2 (also known as HER2, MLN19, NEU, NGL) gene (Gene ID: 2064) in human. ErbB2 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 23-652), a transmembrane domain (aa 653-675), and a cytoplasmic domain (aa 676-1255). Its tyrosine kinase domain is localized to amino acids 720-987. It can also be translocated to the nucleus and its nuclear localization signal resides in amino acids 676-689. It has intrinsic protein tyrosine kinase activity and it mediates the lateral signal transduction of all ErbB receptors. It is involved in in the regulation of a variety of cellular functions, including cell growth, differentiation, and apoptosis. It also regulates outgrowth and stabilization of peripheral microtubules. In the nucleus it is involved in transcriptional regulation and associates with the 5′-TCAAATTC-3′ sequence in the PTGS2/COX-2 promoter and activates its transcription. It is also implicated in transcriptional activation of p21. ERBB2 gene is reported to be overexpressed in about 30% of all human breast carcinomas. ErbB2 is activated by dimerization and autophosphorylation. Ligand-binding is shown to increase phosphorylation on tyrosine residues. This ZooMAb^® 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 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.

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.
