Human Melanopsin (OPN4) ELISA Kit

Designed for the precise measurement of melanopsin (OPN4) in human biological samples, this Sandwich ELISA Kit from Assay Genie supports research in neuroscience, ophthalmology, and chronobiology. The assay is reactive with human samples and accepts serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids, with specificity for natural and recombinant human Melanopsin.

The kit offers a detection range of 78-5000pg/mL and a sensitivity of 40.2pg/mL. Reported precision values are 8.4% intra-assay CV and 10.6% inter-assay CV. Melanopsin is a photopigment expressed in a subset of retinal ganglion cells and is involved in non-image-forming visual functions including circadian rhythm regulation, pupil constriction, and the pupillary light reflex. The target protein, UniProt Q9UHM6, is a multi-pass membrane protein located in the cell membrane with a reported molecular weight of 55 kDa, functioning as a photoreceptor required for circadian rhythm regulation and the pupillary reflex.
