Used in biomedical research to measure Retinol Binding Protein 4 levels in rabbit biological samples such as serum, plasma, or tissue homogenates. Enables researchers to study metabolic disorders, insulin resistance, and kidney function in rabbit models. Commonly applied in endocrinology and nephrology studies where RBP-4 serves as a biomarker for early detection of metabolic and renal dysfunction. The kit provides a reliable, sensitive, and quantitative assessment of RBP-4, supporting investigation into disease mechanisms and therapeutic interventions.
