Used in molecular biology for reverse transcription reactions, enabling the conversion of RNA into complementary DNA (cDNA). It provides optimal pH and ionic conditions for reverse transcriptase enzymes to function efficiently. Commonly used in RT-PCR workflows for gene expression analysis, viral load testing, and RNA virus detection. Supports high yield and accuracy in cDNA synthesis when combined with primers and nucleotides. Stable under recommended storage conditions, ensuring consistent performance across sensitive RNA amplification applications.
