Fig. 4From: Development of a reverse transcription droplet digital PCR (RT-ddPCR) assay for sensitive detection of simian immunodeficiency virus (SIV)SSIV test. The condition combination was SSIV with gene specific priming (a 1 μg Rhesus macaque RNA background; b SIV RNA standard spiked in 1 μg Rhesus macaque RNA background). The ddPCR step of both reactions was performed with MGB probe assays. Detailed experimental conditions are listed in Table 1Back to article page
