An in situ assay able to detect hormonally stimulated or inhibited adenylyl cyclase (AC) activity on as few as 5,000 cells/well has been developed. In addition the assay monitors phosphatase activity which serves as a marker for cell density. Cells are plated in replicate wells at least one day before the assay, and the medium containing AC reagents, an ATP(More)
Human genomic DNA and the HSV tk gene were cotransfected into mouse Ltk- cells and assayed for the acquisition of a Gs-coupled receptor to obtain cell lines expressing human receptors that are so far unavailable. The transfected cells were distributed into 96-well microtitration plates at a density such that after HAT (100 microM hypoxanthine, 1 microM(More)
