Used in biomedical research to quantify levels of cyclophilin B (CyPB) in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit helps investigate inflammatory processes, immune responses, and diseases where CyPB is implicated, including rheumatoid arthritis, sepsis, and certain viral infections like hepatitis C and HIV. It enables researchers to monitor CyPB release from cells under stress or activation, supporting studies on cellular signaling, protein trafficking, and potential biomarker development for disease diagnosis or progression.
