REDscript(TM) M-MLV Reverse Transcriptase (H-)

REDScript(TM) M-MLV Reverse Transcriptase, is an RNA-dependent DNA polymerase that synthesizes cDNA first strand from a single-stranded RNA template to which a primer has been hybridized. M-MLV RT will also extend primers hybridized to single-stranded DNA. This RT endures high temperature better than M-MLV RT. It can retain 100% activity at 50℃, and > 75% activity at 55℃.

More info

REDScript(TM) M-MLV Reverse Transcriptase, encoded by Moloney Murine Leukemia Virus (MMLV RT) is an RNA-dependent DNA polymerase that synthesizes the complementary DNA (cDNA) first strand from a single-stranded RNA template to which a primer has been hybridized. M-MLV RT will also extend primers hybridized to single-stranded DNA. Second strand cDNA synthesis can be achieved from some mRNA templates without an additional DNA polymerase. The difference between this to the general M-MLV RT is that the capacity to endure the heat is enhanced. It can remain the 100% activity at 50℃, it can also keep more than 75% activity at even at 55℃.
