Description
The Retinol Binding Protein (RBP) ELISA Kit from Arbor Assays provides a dual-format competitive assay for measuring RBP in human serum, plasma, urine, and dried blood spots (DBS). This highly conserved protein reflects vitamin A status and renal function, making it valuable in nutritional and kidney health research. The kit features two assay formats: a 10 µL protocol for serum/plasma (range: 7.813–1,000 ng/mL), and a 100 µL protocol for urine/DBS (range: 1.563–200 ng/mL). With sensitivities down to 1.36 ng/mL, this fast, 1.5-hour colorimetric assay is ideal for use in both clinical research and field research applications
