产品概述
产品详情
Species: Human
Host Species: E. coli
MW: 7 kDa
Genbank #: Q8WWG1
a.a: 5–65
Background:
Neuregulins (NDF, heregulin, GGF ARIA, or SMDF) are EGF- like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells.
Description:
Recombinant human Neuregulin-4 EGF domain is a disulfide-linked monomeric protein consisting of 62 amino acid residue subunits, and migrates as an approximately 7 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Neuregulin-4 EGF domain was expressed in E. coli.
UniProt
Q8WWG1
Synonym(s):
Neuregulin-4
Purity:
≥96% by SDS-PAGE and HPLC
Endotoxin Level:
<0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity:
The ED50 was determined by the phosphorylation of ErbB2 and ErbB4 receptors in CHO cells, and was found to be <3ng/ml, corresponding to a specific activity of 3x 105 Units/mg.
Formulation:
Lyophilized from a 0.2 µm filtered 20 mM phosphate buffer, pH 6.0.
Format:
lyophilized protein
Reconstitution:
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability:

The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.

Warning(s):
Avoid freeze/thaw cycles
