Used in biomedical research to detect and quantify PH-20 (SPAM1) protein levels in biological samples. This ELISA kit is particularly applied in reproductive biology studies, where PH-20 plays a role in sperm-egg interaction and fertilization. Researchers use it to investigate male fertility, sperm function, and potential targets for contraceptive development. The kit enables high-sensitivity measurement in cell lysates, tissue extracts, or other sample types relevant to reproductive health research.
