Used in research settings to measure testosterone levels in rabbit biological samples such as serum, plasma, or tissue homogenates. This immunoassay kit enables endocrine studies related to reproductive physiology, hormonal regulation, and metabolic research in rabbits. It is commonly applied in veterinary research, academic studies, and pharmaceutical development to assess testicular function, monitor hormone fluctuations during breeding cycles, or evaluate the impact of drugs or environmental factors on androgen production. The assay provides a sensitive and specific quantitative measurement, supporting investigations into male fertility, stress responses, and hormonal disorders in rabbit models.
