Fig. 4From: Characterization of minority HIV-1 drug resistant variants in the United Kingdom following the verification of a deep sequencing-based HIV-1 genotyping and tropism assayHIV-1 coreceptor tropism determination using Sanger sequencing or DEEPGEN™. The percentage of CCR5- (R5) or CXCR4- (X4) tropic HIV-1 variants in each patient -determined with DEEPGEN™- is indicated in the plots. Green and red blocks in the boxes above each plot (patient cohort) indicate the absence or presence of non-R5 (X4) viruses, respectively, as determined by Sanger sequencing or DEEPGEN™. n.d., not determinedBack to article page
