Molecular diagnosis is a diagnostic technique that uses molecular biological methods to detect changes in the structure or expression level of DNA or RNA in patients. Molecular diagnostic techniques include quantitative PCR, nucleic acid sequence determination, molecular diagnostic techniques based on molecular conformation, and molecular diagnostic techniques of molecular hybridization. Yeasen provides all raw materials of molecular diagnosis, including all IVD enzymes, dNTPs and mix/kit for qPCR and RT-qPCR.
