28 The desired nucleotide replacements were confirmed by Big-Dye version 3.1 (BD Sciences) nucleotide sequencing of the MDR1 open reading frame in recombinant plasmids pKM2-MDR1- V715A, -F716A, -I719A, -G723A, -I764A, -I765A, -I768A, -F770A, -L772A, -T837A, -I840A, -I864A, -I867A, -A871F, -T945A, -M948A, -F983A, -M986A, -V988A, -Q990A, and -V991A.

99 As one can see in Figure 2A, none of the substitutions in TM7 (G723A, I719A, F716A, and V715A) or TM8 (L772A, F770A, I768A, I765A, and I764A) was critical for stimulation of [125 I]IAAP binding by cis-(Z)-flupentixol. Login to comment
