Purity: ≥ 95 % as determined by SDS-PAGE.
Storage: Store at -20℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Background: This protein is a member of the Tyr protein kinase family and the epidermal growth factor receptor subfamily. It a single-pass type I membrane protein with multiple cysteine rich domains, a transmembrane domain, a tyrosine kinase domain, a phosphotidylinositol-3 kinase binding site and a PDZ domain binding motif. The protein binds to and is activated by neuregulins and other factors and induces a variety of cellular responses including mitogenesis and differentiation. Multiple proteolytic events allow for the release of a cytoplasmic fragment and an extracellular fragment. Mutations in this gene have been associated with cancer. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized.
Bio-Activity: Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human NRG1-beta1 at 2 μg/mL (100 μL/well) can bind Recombinant Human HER4/ErbB4, the EC50 of HER4/ErbB4 is 20.99 ng/mL.|2.Measured by its binding ability in a functional ELISA.Immobilized Human ErbB4/Her4 Antibody at 1μg/mL (25 μL/well) can bind Human ErbB4/Her4 with a linear range of 0.46-14.6 ng/mL.
