Used in biomedical research to quantify levels of hematopoietic prostaglandin D synthase (PGDS) activity in biological samples such as cell lysates, tissue homogenates, and body fluids. This ELISA kit enables researchers to study the role of PGDS in inflammatory responses, allergic reactions, and immune regulation. It is commonly applied in studies related to asthma, allergic rhinitis, and other allergic diseases where PGD2 and its downstream metabolites are involved. The kit supports high-throughput analysis and provides a reliable method for monitoring changes in PGDS activity under experimental or pathological conditions, aiding in the development and evaluation of anti-inflammatory and anti-allergic therapeutics.
