Used for the quantitative measurement of SRM (Sperm Receptor Molecule) activity in human biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess levels of SRM, which plays a role in sperm-egg interaction during fertilization. It is commonly applied in reproductive biology studies, infertility research, and clinical diagnostics to evaluate male and female fertility factors. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of SRM activity in small sample volumes. It is also used in pharmaceutical development to monitor the effects of drugs or treatments on reproductive function.
