M-MLV Reverse Transcriptase (RNase H-) can synthesize a complementary DNA strand using single-stranded RNA or DNA as a template. This product is a mutant strain cloned through genetic recombination, in which the RNase H activity has been removed while further enhancing thermal stability. The enzyme can perform the synthesis of the first strand of cDNA at 55-60°C and is suitable for reverse transcription of RNA templates with complex secondary structures. It exhibits improved efficiency in reverse transcription and the ability to transcribe long template fragments, making it suitable for low-template and low-copy gene reverse transcription, with the capacity to synthesize cDNA of approximately 10 kb in length.
