NRG1 Antibody

Neuregulin 1 (NRG1) interacts with the NEU/ERBB2 receptor tyrosine kinase to increase its phosphorylation on tyrosine residues.Neuregulin 1 (NRG1) was originally identified as a 44-kD glycoprotein that interacts with the NEU/ERBB2 receptor tyrosine kinase to increase its phosphorylation on tyrosine residues. It is known that an extraordinary variety of different isoforms are produced from the NRG1 gene by alternative splicing. These isoforms include heregulins (HRGs), glial growth factors (GGFs) and sensory and motor neuron-derived factor (SMDF) . They are tissue-specifically expressed and differ significantly in their structure. The HRG isoforms all contain immunoglobulin (Ig) and epidermal growth factor-like (EGF-like) domains. GGF and GGF2 isoforms contain a kringle-like sequence plus Ig and EGF-like domains; and the SMDF isoform shares only the EGF-like domain with other isoforms. The receptors for all NRG1 isoforms are the ERBB family of tyrosine kinase transmembrane receptors. Through interaction with ERBB receptors, NRG1 isoforms induce the growth and differentialtion of epithelial, neuronal, glial, and other types of cells.

For short periods of storage (days) store at 4˚ C. For longer periods of storage, store NRG1 antibody at -20˚ C. As with any antibody avoid repeat freeze-thaw cycles.

NRG1 antibody can be used for detection of NRG1 by ELISA at 1:62500. NRG1 antibody can be used for detection of NRG1 by western blot at 0.5 μ g/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
