Air–liquid interface (ALI)’s with a genotype homozygous for the functional form of the T2R38 receptor (PAV/PAV) or a genotype homozygous for the non-functional form of the receptor (AVI/AVI) demonstrated no significant differences in 4-amino-5-methylamino-2′,7′-difluorescein (DAF-FM) fluorescence intensity in response to 0.1% quinine over a period of 7 min (n = 6 cultures per condition). (A) Nitric oxide (NO) release over a period of 5 min, and (B) maximal NO release during that same period.
