Predicted MW | 21.2 kDa |
Concentration | lot specific |
Purity | >95% by SDS-PAGE |
Buffer | Presentation State: Purified State: Liquid purified protein Buffer System: 20 mM Tris 8.0, 0.20 mM NaCl, 0.5 mM DTT, 10% glycerol |
Preparation | Liquid purified protein |
Applications | Protocol: Activity Assay 1. Prepare 170 ul assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 200 mM Tris-HCl, pH 8.0, and 20nM chymotrypsin. 2. Add 10 ul of recombinant Cyclophilin B protein with 1 ug in assay buffer. 3. Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer. 4. Add 20 ul pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM) 5. Record the increase in A405 nm for 30 minutes at 25°C. |
Protein Description | Recombinant human cyclophilin B was expressed in E.coli and purified by using conventional chromatography techniques. |
Storage | Store undiluted at 2-8°C for up to two weeks or (in aliquots) at -20°C or -70°C for longer. Avoid repeated freezing and thawing. |
Stability | Shelf life: one year from despatch. |
Bioactivity | Specific: > 220 nmoles/min/mg, defined as the amount of enzyme that cleaves 1 umole of suc-AAPF-pNA per minute at 25°C in Tris-HCl pH 8.0 using chymotrypsin. |
Endotoxin | < 1.0 EU per 1 microgram of protein (determined by LAL method) |

Summary | The protein encoded by this gene 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. Variants have been identified in this protein that give rise to recessive forms of osteogenesis imperfecta. [provided by RefSeq, Oct 2009] |
