Used in research to measure 11-ketotestosterone levels in mouse biological samples such as serum, plasma, or tissue extracts. This ELISA kit enables scientists to study androgen regulation in male development, reproductive physiology, and neuroendocrine function in mice. It is particularly useful in studies related to steroidogenesis, sexual differentiation, and the role of 11-KT in aggressive behavior, social dominance, and gonadal function. The assay provides a sensitive and specific method for quantifying 11-KT in experimental models, supporting endocrinology and behavioral research.
