Used in biomedical research to measure levels of human calcium phosphatase (also known as calcineurin) in biological samples such as blood, serum, or cell lysates. This kit enables researchers to study calcineurin activity indirectly by quantifying its concentration, which is important in understanding immune response regulation, neuronal signaling, and cardiac function. It is commonly applied in studies related to autoimmune diseases, transplant rejection, neurodegenerative disorders, and drug development targeting calcineurin pathways. The ELISA format allows for high sensitivity, specificity, and throughput in experimental settings.
