Peptidyl-prolyl cis-trans isomerase B, PPIase B, CYP-S1, Cyclophilin B, Rotamase B, S-cyclophilin, SCYLP.
Cyclophilin B (also known as PPIB, peptidylpropyl isomerase B) is a cyclosporine-binding protein and is mainly located within the endoplasmic reticulum. It is associated with the secretory pathway and released in biological fluids. This protein can bind to cells derived from T- and B-lymphocytes, and may regulate cyclosporine A-mediated immunosuppression.
Cyclophilin B Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 207 amino acids (34-216 a.a) and having a molecular mass of 22.7kDa.
Cyclophilin B is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Cyclophilin B protein solution (1mg/ml) containing Phosphate Buffered Saline (pH7.4) and 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
