Used in biomedical research to quantify levels of human androgen-induced protein (PS2) in biological samples such as serum, plasma, or tissue extracts. The kit enables researchers to study the role of PS2 in hormone-responsive cancers, particularly breast cancer, where PS2 expression is linked to estrogen receptor activity. It supports investigations into cancer progression, response to hormonal therapy, and development of diagnostic markers. The ELISA format allows for high sensitivity and specificity, making it suitable for clinical research and laboratory studies focused on endocrine-related diseases.
