Human RTBDN (Retbindin) ELISA KIT (HUFI04914)

Retbindin (RTBDN) is a retina-specific binding protein expressed predominantly in photoreceptor cells, where it interacts with retinol and contributes to the visual cycle of vitamin A metabolism. This Human RTBDN ELISA Kit from Assay Genie enables quantitative measurement of Retbindin in human liquid specimens on a microplate format with colorimetric readout. The assay is intended for research use only and supports investigations into retinal biology, photoreceptor function, and conditions such as retinitis pigmentosa and age-related macular degeneration. Each kit supplies the components needed for 96 determinations, including pre-coated plate wells, lyophilized standards, biotinylated detection antibody, and assay buffer. Researchers should equilibrate reagents to room temperature before use and store the kit refrigerated at 4 degrees C; reconstituted standards should be aliquoted and kept frozen to limit freeze-thaw cycles. A sample volume of 50 uL is recommended per well, with a standard curve calibrated to the low ng/mL range. The capture antibody is human-specific, and no significant cross-reactivity has been observed with homologous retinal proteins from other species, making this kit a useful reagent for studies of human ocular physiology and retinoid metabolism.
