Type: Binding

Description: Inhibition Assay: Full-length human GCGR (Accession Number: NM000160) subcloned into pcDNA3.1 was stably transfected into HEK293 cells (hGluc-1 HEK) and maintained under G418 selection (500 ug/mL). Cell cultures were maintained in DMEM/F12 media supplemented with 10% FBS and 1% GlutaMax. Membranes were prepared from these cells as follows: cells were harvested from T225 flasks and re-suspended in hypotonic lysis buffer, 50 mM HEPES pH 7.4 supplemented with Complete Protease inhibitors (Boehringer Mannheim, Indianapolis, Ind.). Cells were dounced 20 times on ice and spun at 700xg to remove nuclei and unlysed cells. The resulting pellet was re-suspended in hypotonic lysis buffer and the above step was repeated. Supernatants from the low speed centrifugation were combined and subsequently spun at 100Kxg for 1 hr at 4 C. and the resulting pellet was re-suspended in buffer containing 50 mM HEPES pH 7.4 and 10% sucrose and the protein concentration was adjusted at 1 mg/mL as determined in the BCA assay.
