Human RBP1/Retinol-binding protein 1 ELISA Kit

Designed for the precise quantification of retinol-binding protein 1 levels in human samples, this Sandwich ELISA from Assay Genie uses a colorimetric, double-antibody format and is validated for use with serum, plasma, cell culture supernatants, cell or tissue lysates, and other liquid samples. Retinol-binding protein 1 is a transporter that binds retinol (vitamin A) and contributes to vitamin A metabolism and homeostasis; dysregulation has been linked to vitamin A deficiency, liver disease, and metabolic disorders, making it a valuable biomarker for research into these conditions.

The kit shows a sensitivity of 0.188 ng/mL and a detection range of 0.313–20 ng/mL, with storage at 2-8°C for 12 months. Reported recovery is 88–100% (average 95%) for serum, 86–103% (average 93%) for EDTA plasma, and 88–103% (average 96%) for heparin plasma, and linearity ranges from 85–99% to 90–105% (serum), 87–96% to 83–100% (EDTA plasma), and 86–99% to 84–100% (heparin plasma) across serial dilutions.
