Used in biomedical research to measure levels of Prostaglandin D2 Synthetase (PTGDS) in biological samples such as serum, plasma, cerebrospinal fluid, and tissue homogenates. The kit enables researchers to quantify PTGDS protein expression in studies related to inflammation, allergic responses, asthma, and neurodegenerative diseases like Alzheimer's and Parkinson's. It is also applied in sleep research since PTGDS is involved in the regulation of non-REM sleep. The assay supports high sensitivity and specificity, making it suitable for clinical and preclinical investigations into disease mechanisms and therapeutic development.
