A Rapid Integrated Detection Platform for Genes Related to Duck Muscle Tissue Development

In duck breeding, the growth and development of skeletal muscle is an important factor influencing the meat production performance of ducks. Therefore, the determination of Myod and Myf5 gene expression in poultry skeletal muscle tissues can help to understand the muscle development of poultry, improve the production performance and feed conversion rate of animal organism, enhance the rapid protein deposition in animal organism, and obtain high quality and quantity of animal livestock products. In this study, a fluorescent PCR assay system for Myod and Myf5 genes was developed, and a dual integrated rapid detection platform suitable for detecting Myod and Myf5 genes in poultry muscle tissue with a sensitivity of 10 copies/μL was constructed using a set of commercial, fully automated nucleic acid analyzer with integrated detection based on magnetic bead method for nucleic acid extraction and PCR fluorescence detection. For 20 simulated samples, the integrated detection system was consistent with the results of qPCR experiments after conventional laboratory extraction, while the closed cassette-based detection reduced the chance of contamination occurrence, making the results more reliable and accurate, which is ideal for immediate on-site rapid detection.
