Advanced Targeting Systems announces the release of Melanopsin-SAP (Cat. #IT-44), a reagent that specifically eliminates intrinsically photosensitive retinal ganglion cells (ipRGCs) that contain melanopsin. This material is described in Göz et al. and consists of an antibody to an extracellular domain conjugated to saporin. The ipRGCs, with their amazing long processes, have become major players in the perception of light and dark, and their role as circadian rhythm determinants is a hot topic. Use this new tool to determine who’s right!
