Fig. 4From: Effect of Pregnane X Receptor*1B genetic polymorphisms on postoperative analgesia with fentanyl in Chinese patients undergoing gynecological surgeryThe DNA sequence of PXR8055C > T. Genomic DNA was extracted using a conventional phenol-chloroform procedure. Genotyping of PXR8055C > T allele was conducted by polymerase chain reaction (PCR), direct sequencing. PXR*1B haplotype was genotyped by PHASE V.2.1 software. Two C bases were showed in the PXR8055C > T wild homozygotes. One T base and one T base were showed in the PXR8055C > T heterozygotes. Two T bases were showed in the mutant homozygotesBack to article page
