Retinol-Binding Protein (RBP) is a small transport protein synthesized primarily in the liver, responsible for carrying retinol (vitamin A) throughout the body. It is a sensitive biomarker for evaluating renal tubular function, vitamin A status, and hepatobiliary system health. Our RBP assay kit is engineered to provide rapid and highly specific measurements of RBP concentrations in biological samples, addressing the clinical and research needs for detecting RBP abnormalities. Abnormal RBP elevation is closely associated with impaired renal tubular function, diabetic nephropathy, lupus nephritis, overnutrition, fatty kidney disease, as well as vitamin A deficiency, hepatobiliary diseases, malabsorption syndrome, and obstructive jaundice. With its superior performance, our RBP kit is an indispensable tool for medical diagnostics, nutritional research, and drug development.

The kit uses monoclonal antibodies specifically targeting RBP, eliminating cross-reactivity with other proteins such as albumin and transthyretin. It ensures accurate detection even in complex sample matrices like urine and cerebrospinal fluid.
Unlike many RBP kits limited to serum samples, our product supports the detection of RBP in serum, urine, and cerebrospinal fluid. This versatility expands its application scope in both clinical and research settings.
The kit’s reagents are formulated with advanced stabilizers to prevent degradation during storage and use. Intra-assay coefficient of variation (CV) is less than 5%, and inter-assay CV is less than 8%, ensuring consistent results across different experiments.
It is a first-line tool for screening and monitoring renal tubular dysfunction, diabetic nephropathy, and lupus nephritis. Urine RBP detection is more sensitive than traditional indicators like creatinine, enabling early diagnosis of renal injury.
The kit accurately measures serum RBP levels to evaluate vitamin A nutritional status, which is crucial for diagnosing vitamin A deficiency in children, pregnant women, and patients with malabsorption syndrome.
Researchers use the kit to study the impact of hepatobiliary diseases on RBP synthesis and secretion. It is also applied in nutritional science to investigate the relationship between RBP levels and dietary fat intake, aiding in the development of personalized nutrition plans.
Our RBP kit adopts high-affinity monoclonal antibodies developed through phage display technology, ensuring unparalleled specificity and sensitivity. The antibody production process complies with GMP standards to guarantee batch consistency.
We offer free sample testing services for new customers, allowing you to verify the kit’s performance before purchase. Our after-sales team provides detailed result interpretation guides and on-site training for large-scale users.
We can tailor the kit’s linear range and sample volume requirements according to your specific research needs. For industrial customers, we provide large-scale bulk production with flexible delivery schedules to meet your project timelines.
RBP is filtered by the glomerulus and almost completely reabsorbed and degraded by the renal tubules. Even mild tubular damage will cause a significant increase in urine RBP levels, making it a more sensitive indicator than traditional markers like β2-microglobulin.
Yes, serum RBP levels can be affected by recent dietary fat intake. We recommend collecting fasting blood samples (at least 8 hours without food) to ensure accurate evaluation of vitamin A status and renal function.
Absolutely. The kit’s 96-well plate format is ideal for high-throughput testing, and the simple operation procedure reduces labor costs. It is widely used in hospital laboratories for routine renal function and nutritional status screening.
