Used in research settings to detect and quantify Rat AF Protein levels in biological samples such as serum, plasma, or tissue homogenates. The kit is commonly applied in studies related to reproductive biology and endocrinology, where AF Protein plays a role in regulating hormone activity and gonadal function. It enables researchers to monitor changes in AF Protein expression under experimental conditions, supporting investigations into fertility, hormonal disorders, and developmental physiology. The ELISA format allows for high sensitivity, specificity, and throughput, making it suitable for both academic and pharmaceutical research.
