Introduction
Canopy FGF Signaling Regulator 4 (CNPY4) is a member of the canopy family, characterized by the presence of a saposin B-type domain. This protein plays a role in regulating the expression of TLR4 on the cell surface.
Description
Recombinant human CNPY4, expressed in E. coli, is a non-glycosylated polypeptide chain. It consists of 252 amino acids (residues 22-248) with a molecular weight of 28.6 kDa. This protein includes a 25 amino acid His-tag fused at the N-terminus and is purified using proprietary chromatographic techniques.
Physical Appearance
Clear, colorless solution that has been sterilized by filtration.
Formulation
CNPY4 protein is supplied in a solution at a concentration of 0.25 mg/ml. The solution is buffered with 20mM Tris-HCl at pH 8.0 and contains 0.2M NaCl, 50% glycerol, 5mM DTT, and 2mM EDTA.
Stability
For short-term storage (up to 2-4 weeks), keep refrigerated at 4°C. For extended storage, freeze at -20°C. The addition of a carrier protein such as 0.1% HSA or BSA is recommended for long-term storage. Repeated freezing and thawing should be avoided.
Purity
The purity of CNPY4 is determined to be greater than 85.0% using SDS-PAGE analysis.
Synonyms
PRAT4B, Protein canopy homolog 4, CNPY4.
