Give Your Sample Prep a Boost! Introducing Biochain UltraScriptTM Reverse Transcriptase and M-MLV Reverse Transcriptase.

UltraScriptTM Reverse Transcriptase

- Cat # L4121050, L4121100

  • Thermostable Activity ‐ performs reverse transcription throughout a wide range of 42°C ~ 65°C
  • Enhanced Performance – handles high and low RNA concentrations, short and long RT target sizes
  • Reproducibility ‐ strict controlled production/purification ensures reproducible results
  • Stability ‐ stable at room temperature for a month, one year at 4°C and for 2 years in a ‐20°C freezer

    Figure 3. Comparison of UltraScript RT and Supplier I RT on a 12kb human Titin ORF. qPCR was performed to quantify the synthesized first strand Titin cDNA using primers targeted at a specific region (11561‐11737 bp) of reverse transcribed Titin cDNA.


    M-MLV Reverse Transcriptase

    Cat # K5040002, K5040002-100K

  • Minimized RNaseH activity
  • Long RNA template reverse transcription ability (>5kb)
  • Reaction temperature ranges between 42 °C -50 °C
