Figure 3From: Reverse transcriptase droplet digital PCR shows high resilience to PCR inhibitors from plant, soil and water samplesMean copies per partition (lambda) determined in the control sample (NIC) with no inhibitor added and in the samples spiked with serial dilutions of the inhibitor extracts from the selected matrices and from the chemical inhibitors. H, M, L, (VL), high, medium, low (and very low) concentrations of inhibitors, respectively. Black line denotes the mean value of lambda for NIC.Back to article page
