A novel SHSY5Y/ NK1R-tGFP cell line has been developed through stable transfection to modulate the internalization of the Neurokinin 1 receptor (NK1R) complex in living cells and to assay for compounds inducing NK1R-tGFP redistribution inside the cells.Fluorescent NK1R Cell Line was obtained by transfection of an expression vector for a fusion protein of tGFP and human NK3R, as well as G418 into SHSY5Y cells. Single cells with strong green fluorescence were selected by flow cytometry, and allowed to expand. These cells constitutively express the tGFP- NK1R fusion protein.Assay Details: Innoprot NK1R Internalization Assay Cell LIne has been designed to assay compounds or analyze stimuli for their ability to modulate NK1R receptor activation and the following redistribution process inside the cells. This highly reproducible assay allows monitoring NK1R receptor activation and internalization process using High Content Analysis and fluorescence microscope applications. This internalization assay has been validated with an average of Z=0.69+/- 0.01 for High Content Screening.
