Detection of Human/Mouse/Rat Cyclophilin B by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, A431 human epithelial carcinoma cell line, BaF3 mouse pro-B cell line, PC-12 rat adrenal pheochromocytoma cell line, Rat-2 rat embryonic fibroblast cell line, and NRK rat normal kidney cell. PVDF membrane was probed with 1 µg/mL Mouse Anti-Human/Mouse/ Rat Cyclophilin B Monoclonal Antibody (Catalog # MAB5410) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human Cyclophilin A and Cyclophilin B (5 ng/lane) were included. A specific band for Cyclophilin B was detected at approximately 24 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.
Cyclophilin B in HeLa Human Cell Line.
Cyclophilin B was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human/Mouse/Rat Cyclophilin B Monoclonal Antibody (Catalog # MAB5410) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Cyclophilin B
Cyclophilin B (SCYLP, CyPB and peptidyl-prolyl cis-trans isomerase B) is a 24 kDa glycoprotein member of the B subfamily of the cyclophilin-type PPIase family of molecules. It is both secreted and retained in the ER. When secreted, Cyclophilin B mediates chemotaxis and T cell adhesion to fibronectin. This is likely due to its prolyl cis/trans isomerase activity. Intracellularly, Cyclophilin B appears to serve as a molecular chaperone for molecules destined for secretion. It does so via stabilization, and facilitating the activity of additional chaperones. The human Cyclophilin B precursor is 216 amino acids (aa) in length. It contains a 25 aa signal sequence plus a 191 aa mature region. There is a partial heparin-binding sequence (aa 27‑34), a PPIase domain (aa 47‑204) and a C-terminal ER retention motif (aa 213‑216). Over aa 34‑216, the human and mouse sequences are 95% aa identical.
