| Description: | Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM 001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM 001526) were grown to confluency in DMEM (Hyclone, cat # SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2Kx G, 5 min at 4 C.), the supernatant was aspirated and the pellets frozen and stored at -80 C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. |
