NRG3 Protein, Human, Recombinant (His Tag)

NRG3 (Neuregulin 3) is a Protein Coding gene. NRG3 is a member of the neuregulin family of EGF proteins. It has been shown to activate the tyrosine phosphorylation of its cognate receptor, ERBB4, and is thought to influence neuroblast proliferation, migration and differentiation by signaling through ERBB4. NRG3, a brain-enriched neurotrophin, undergoes alternative splicing and is implicated in several neurological disorders with developmental origins. It also promotes mammary differentiation during embryogenesis. NRG3 promotes early mammary morphogenesis and acts during specification of the mammary placode, an aggregate of epithelial cells that form during mid-embryogenesis. Diseases associated with NRG3 include Schizophrenia and Schizoaffective Disorder.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
