Melanopsin Antibody Recent Publications

We’re highlighting one of our antibodies, a rabbit polyclonal against Melanopsin. This antibody is offered as both serum (AB-N38) and affinity purified (AB-N39). Intrinsically photosensitive retinal ganglion cells (ipRGCs) are cells that express melanopsin. These ipRGCs, with their long processes, are involved in the perception of light and dark and are circadian rhythm determinants. Our Melanopsin antibody recognizes a portion of the N-terminal region of the mouse melanopsin extracellular domain and does not cross-react with melanopsins of other species, so it’s specific to mouse.

Here is how other researchers are using them in recent publications. This Melanopsin antibody may be the antibody your lab needs.

Kim et. al. used (AB-N38) at a 1:2,000 dilution to quantify ipRGCs in the retina and confirm that Per1-deficiency did not affect melanopsin-positive cell abundance.
