General description
Neuregulin-1(UniProt: Q02297; also known as Pro-NRG1, Acetylcholine receptor-inducing activity, ARIA, Breast cancer cell differentiation factor p45, Glial growth factor, Heregulin, HRG, Neu differentiation factor, Sensory and motor neuron-derived factor) is encoded by the NRG1 (also known as GGF, HGL, HRGA, NDF, SMDF) gene (Gene ID: 3084) in human. Neuregulin-1 is a single-pass type 1 membrane protein that acts as a direct ligand for ErbBB3 and ErbB4 tyrosine kinase receptors. It concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. Eleven isoforms of Neuregulin-1 are known that are produced by alternative splicing. They have been classified as type I (isoforms with an Ig domain and a glycosylation domain) type II NRGs (isoforms with an Ig domain, but no glycosylation domain). These multiple isoforms perform diverse cellular functions, such as inducing growth and differentiation of epithelial, glial, neuronal, and skeletal muscle cells and inducing expression of acetylcholine receptor in synaptic vesicles during the formation of the neuromuscular junction. Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form. Dual cleavage of Neuregulin-1 by beta-secretase 1 (BACE1) and ADAM17 is shown to liberate EGF-like domain, which stimulates ErbB3 signaling. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Fleck, D., et a. (2013). J. Neurosci. 33(18); 7856-7869).
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.
We are committed to bringing you greener alternative products, which adhere to one or more of the 12 Principles of Green Chemistry. This antibody is preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed, and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency".

Biochem/physiol Actions
Clone 1G5 is a ZooMAb® recombinant rabbit monoclonal antibody that specifically detects NRG1. It targets an epitope within 25 amino acids from the N-terminal half.
Physical form
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.
Preparation Note
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.
