General description: Reverse Transcriptase, AMV is a gene product of the RNA genome of avian myeloblastosis virus. The enzymatically active forms of the purified enzyme are alpha,betabeta and alphabeta. The molecular weight of the alpha-subunit is 68 kDa, that of the beta-subunit 92 kDa. The mature alphabeta form, the most active form of Reverse Transcriptase, AMV, includes a RNA-directed DNA polymerase, a DNA-dependent DNA polymerase, a RNase H, and an unwinding activity. Reverse Transcriptase, AMV is used for cDNA synthesis, for synthesis of first strand cDNA for use in subsequent amplification reactions and dideoxy DNA sequencing.The enzyme can also be used for RNA sequencing, 3' end labeling of DNA fragments, and the generation of ss probes for genomic footprints.Reverse Transcriptase AMV requires a primer and Mg2+ or Mn2+ for activity.

Application: Reverse Transcriptase AMV is used for:. First- and second-strand cDNA synthesis and synthesis of first strand cDNA for use in subsequent amplification reactions. Dideoxy DNA sequencing. Primer extension. RNA sequencing. 3G¦-end labeling of DNA fragments. Generation of single-stranded probes for genomic footprint experiments

Quality: Absence of contaminants: Tested for the absence of detectable nonspecific RNases and nonspecific DNases in incubations with various nucleic acids (analyzed by gel electrophoresis) according to the current Quality Control procedures.Function test: Reverse Transcriptase AMV is function tested in the cDNA Synthesis Kit and RT-PCR.

Specificity: AMV (Avian Myeloblastosis Virus) Reverse Transcriptase is an RNA-directed DNA polymerase and a DNA-dependent DNA polymerase. The AMV reverse transcriptase requires a primer and Mg2+ or Mn2+ for activity.Heat inactivation: 5 min, 95 C
