Detection of Human, Mouse, and Rat Cyclophilin A by Western Blot.
Western blot shows lysates of MOLT‑4 human acute lymphoblastic leukemia cell line, HeLa human cervical epithelial carcinoma cell line, C2C12 mouse myoblast cell line, Nb2‑11 rat lymphoma cell line, and BaF3 mouse pro-B cell line. PVDF membrane was probed with 0.1 µg/mL of Rat Anti-Human Cyclophilin A Monoclonal Antibody (Catalog # MAB3589) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Cyclophilin A at approximately 18 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Cyclophilin A in PANC-1 Human Cell Line.
Cyclophilin A was detected in immersion fixed PANC-1 human pancreatic carcinoma cell line using Rat Anti-Human Cyclophilin A Monoclonal Antibody (Catalog # MAB3589) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Cyclophilin A
Cyclophilin A, also called Peptidyl-prolyl Isomerase A, PPIA, CYPA, and CYPH, was originally characterized for its ability to catalyze the transition between cis- and trans- proline residues critical for proper folding of proteins (1). Cyclophilin is also incorporated into many viruses, including HIV-1, where it has been speculated to be involved in functions such as viral assembly and infectivity (2). The immunosuppressive activity of cyclosporins has been correlated with their ability to form complexes with cyclophilins that inhibit calcineurin phosphatase activity (3) and prevent incorporation of cyclophilin into viral particles (4). The cyclosporin/cyclophilin complex selectively binds and inactivates calcineurin (3, 5), making it a useful inhibitor for studying calcineurin activity.
