Figure 1. Evaluation of the One-Step RT-qPCR kit demonstrates amplification efficiency and reproducible performance. RT-qPCR targeting Listeria spp. was performed using the One-Step RT-qPCR Kit with five input RNA concentrations (0.1–1000 pg; 3 technical replicates per input). Reactions were performed according to the recommended protocol (A) Amplification plots show robust amplification across the entire RNA input range with minimal variation between technical replicates, demonstrating high assay reproducibility. (B) Mean Ct values, Ct standard deviations(Ct SD), endpoint fluorescence (RFU), and RFU standard deviations(RFU SD) for each input concentration. Low Ct variability and consistent fluorescence signals across the dilution series indicate high assay precision. (C) Standard curve generated from the mean Ct values demonstrates linearity over five orders of magnitude (R² = 0.999), with a calculated PCR efficiency of 100.8%, supporting accurate quantitative detection across the tested input range.
The kit provides consistent, high-performance amplification of major aquaculture viruses, guaranteeing precise and reliable detection

Figure 2. Performance evaluation of the One Step RT-qPCR Kit for key salmonid viral pathogen detection. The One Step RT-qPCR Kit demonstrates amplification of major salmonid viruses, including Infectious Salmon Anemia Virus (ISAV), Piscine Orthoreovirus (PRV), and Infectious Pancreatic Necrosis Virus (IPNV) at medium (IPNV++) and high (IPNV+++) viral loads. (A) Representative amplification curves exhibit the expected sigmoidal profiles for all viral targets, confirming reliable detection across different viral targets. (B) The summary table shows mean Ct values ranging from 15.57 to 31.41 with low Ct standard deviations(Ct SD).
Achieve faster, more sensitive results. The One Step RT-qPCR Kit consistently detects viral targets 5.6 to 6.8 cycles earlier than the competition.

DeCodiFi™ High-Fidelity Polymerase is designed for broader high-fidelity PCR and sequencing workflows. DeCodiFi™ Alpha is designed specifically for ultra-high fidelity NGS library amplification, with emphasis on polymerase error rate, coverage uniformity, low-input performance, and library complexity.
Evaluate polymerase error rate, coverage uniformity, GC bias, library yield, input DNA requirements, overcycling tolerance, and compatibility with your downstream sequencing workflow.
DeCodiFi™ Alpha is designed to reduce polymerase-introduced errors during NGS library amplification. In draft performance data, DeCodiFi™ Alpha was evaluated against multiple high-fidelity polymerase mixes using error per million in Illumina libraries of the complete E. coli genome.
Yes. DeCodiFi™ Alpha is designed to support uniform coverage across genomic landscapes and help reduce amplification bias during library amplification. Draft performance data includes coverage analysis from E. coli Illumina libraries.
DeCodiFi™ Alpha is designed to support low-input library amplification workflows, showing robust library yields from 5 pg DNA under tested conditions.
DeCodiFi™ Alpha is positioned for demanding short-read NGS applications. For long-read sequencing or long-fragment amplification workflows, DeCodiFi™ Long&Complex may be a more relevant starting point.
Yes. Our team can help evaluate whether DeCodiFi™ Alpha fits your NGS library amplification workflow, especially if you are working with low-input DNA, amplification bias, overcycling, or variant-sensitive applications.
