| Description: | Cell Culture Conditions: CHO-K1 cells previously transfected with G-alpha 16 were subsequently transfected with the human CRTH2 receptor and the neomycin resistance gene. Following selection in 800 ug/mL G418 (geneticin), individual clones were assayed for their receptor expression based on staining with an anti human CRTH2 IgG, followed by assaying for their response to 13,14-dihydro-15-keto Prostaglandin D2 (DK-PDG2) (ligand) in the Ca2+ Flux assay. Positive clones were then cloned by limiting dilution cloning. The transfected cells were cultured in Ham's F-12 medium supplemented with 10% fetal bovine serum, 2 mM glutamine, 100 U/mL penicillin/100 ug/mL streptomycin, 200 ug/mL hygromycin B, and 800 ug/mL G418 (geneticin). Cells were harvested with trypsin-EDTA (trypsin-ethylenediaminetetraacetic acid) and counted using ViaCount reagent (from Guava Technologies, Inc. which contains two DNA-binding dyes. |
