Recombinant human NRG4, His-tagged

• Cat.No.: NRG4-2472H
• Product Overview: Recombinant human NRG4 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Description: NRG4 belongs to the neuregulin family and contains 1 EGF-like domain. The protein is low affinity ligand for the ERBB4 tyrosine kinase receptor. It concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. NRG4 does not bind to the ERBB1, ERBB2 and ERBB3 receptors.
• Form: Liquid. In 20mM Tris-HCl(pH8.0) containing 30% glycerol, 0.15M NaCl, 1mM DTT
• Molecular Mass: 9.1kDa (84aa) confirmed by MALDI-TOF
• AA Sequence: MGSSHHHHHH SSGLVPRGSH MGSMPTDHEE PCGPSHKSFC LNGGLCYVIP TIPSPFCRCV ENYTGARCEE VFLPGSSIQT KSNL
• Purity: >90% by SDS - PAGE
• Applications: SDS-PAGE
• Storage: Can be stored at +4C short term (1-2 weeks). For long term storage, aliquot and store at -20C or -70C. Avoid repeated freezing and thawing cycles.
• Concentration: 0.25 mg/ml (determined by Bradford assay)
