Used in research laboratories to detect and quantify β-casein protein in biological samples, this ELISA kit is particularly applied in studies related to milk composition, dairy allergies, and mammary gland function in rodent models. It enables researchers to measure β-casein levels in milk or tissue extracts from rats, supporting investigations in lactation biology, nutritional science, and immunology. The assay is valued for its sensitivity and specificity, allowing accurate measurement even in complex sample matrices. It is commonly used in preclinical studies assessing mammary development, lactation disorders, or the effects of hormonal regulation on milk protein production.
