| Comments: | Cell line creation and culture of the human mGluR4/ Gqi5/CHO line. Human mGluR4 (hmGluR4)/CHO cells were stably transfected with the chimeric G protein Gqi5 (Conklin et al., 1993) in pIRESneo3 (Invitrogen, Carlsbad, CA) and single neomycin-resistant clones were isolated and screened for mGluR4-mediated calcium mobilization using the method described below. hmGluR4/CHO cells were cultured in 90 percent Dulbecco's Modified Eagle Media (DMEM), 10 percent dialyzed fetal bovine serum (FBS), 100 units/ml penicillin/streptomycin, 20 mM HEPES (pH 7.3), 1 mM sodium pyruvate, 20 ug/ml proline, 2 mM glutamine, 400 ug/ml G418 sufate (Mediatech, Inc., Herndon, VA) and 5 nM methotrexate (Calbiochem, EMD Chemicals, Gibbstown, NJ). All cell culture reagents were purchased from Invitrogen Corp. (Carlsbad, CA) unless otherwise noted. Potency determinations. Assays were performed within Vanderbilt University's High-Throughput Screening Center. Human mGluR4/Gqi5/CHO cells (30,000 cells/20 ul/we | |
