Thermo Fisher Scientific Applied Biosystems HIV-1 Genotyping Kit

Thermo Fisher Scientific has launched the Applied Biosystems HIV-1 Genotyping Kit, a research-use-only assay that can be used to examine positive samples of HIV to identify genetic variants that resist common antiretroviral therapeutics. The assay is designed for use on Applied Biosystems Sanger sequencing CE instrumentation with HIV RNA extracted from EDTA plasma or dried blood spots, and measures genomic mutations in the protease, reverse transcriptase, and integrase regions of the pol gene, Thermo Fisher said.
