Human RBP2 (Retinol Binding Protein 2) ELISA Kit (HUFI06890)

Quantitative determination of cellular retinol-binding protein 2 (CRBP2, encoded by RBP2), a 134-residue intracellular carrier that solubilizes all-trans-retinol during intestinal absorption and chylomicron assembly. Assay Genie supplies the human-reactive kit in a 96 Assays configuration with pre-coated microplate strips, lyophilized recombinant standards, biotinylated detection antibody, streptavidin-HRP conjugate, and TMB substrate ready for immediate use. Investigators studying vitamin A uptake, gestational nutrition, fat-soluble vitamin status in cystic fibrosis, or retinoid metabolism in inflammatory bowel disease can apply the assay to serum or plasma specimens, with sample volume, dilution factor, and run protocol printed in the package insert. Reconstituted standard should be aliquoted to limit freeze-thaw exposure, while remaining components are kept refrigerated until the kit expiration date printed on each outer carton. Lot-specific intra- and inter-assay coefficients of variation, recovery in spiked matrices, and parallelism data for diluted samples are reported in the Certificate of Analysis that accompanies each shipment.
