Overview:   Cyclophilin B (CyPB) is a cyclosporine-binding protein located mainly within the endoplasmic reticulum.  It has also been detected in the nucleus where it may maintain a gene regulatory role.  Cyclophilin B has a signal sequence and is therefore associated with the secretory pathway and released in biological fluids.   

Given that Cyclophilin B is a soluble protein in the secretory pathway, the primary locations to detect and assay are in biological fluids, such as serum and plasma, cell culture supernatant, and cell and tissue lysates.   Use the isolation methods suggested in the protocol manual to prepare samples using biological fluids and cell culture supernatant.  To assay in cell or tissue lysates, use a non-denaturing lysis buffer to solubilize membranes and suspend intracellular Cyclophilin B into the lysis buffer supernatant.  The  protocol associated with the FIVEphoton Biochemicals ELISA Lysis and Protein Extraction Buffer (Part No. ELSP-1) provides detailed instructions how to isolate intracellular proteins by cell lysis in preparation for ELISA.
