Corticotropin releasing hormone binding protein, CRF-BP, CRH-BP, CRF-binding protein.
Corticotropin Releasing Hormone Binding Protein or CRHBP is a hormone that stimulates the preopiomelanocortin-derived peptides secretion & synthesis. In general, the levels of CRHBP in the human plasma are relatively low. There are times when we can find high levels of the hormone, mainly in pregnancy, after parturition the levels drop back, the high levels are thought to be derived from the placenta. CRH-binding protein can be found in the plasma, this protein inactivates CRH, in order to avoid inappropriate pituitary-adrenal stimulation during gestation.
CRHBP Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 324 amino acids (22-322 a.a) and having a molecular mass of 36.1kDa.
CRHBP is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
CRHBP protein (1mg/ml) contains 10% glycerol, 0.4M urea and 20mM Tris-HCl buffer (pH 8.0).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 85.0% as determined by SDS-PAGE.
