DBscript Turbo Reverse Transcriptase: Ultra-fast thermostable M-MLV mutant

(DB-1333)

Supercharge your reverse transcription workflow with DBscript Turbo, an ultra-fast and highly thermostable M-MLV mutant designed for the most demanding applications. Engineered for unparalleled speed and processivity, it operates ~100-fold faster than its competitors while delivering superior sensitivity.


With optimum activity between 50-60°C and the resilience to perform RT steps at up to 70°C, DBscript Turbo is the ultimate solution for generating full-length cDNA libraries, tackling long transcripts, and rapidly detecting low copy number targets down to a single copy.

Package size

Key Parameters: The best solution for most applications

Unmatched Speed: Performs ~100-fold faster than SuperScript III or III Flash, offering the same rapid synthesis as SuperScript IV but with enhanced sensitivity.

Extreme Thermostability: Features an optimum activity range of 50-60°C and remains highly functional for RT steps at up to an impressive 70°C.

Highly Processive: The ideal enzyme for long transcripts, ultra-short protocols, and full-length cDNA library synthesis.

Maximum Sensitivity: Suitable for low copy number targets, ensuring reliable detection down to ~1 copy.

DBscript shows higher cDNA yield than its competitors

cDNA yield after 5 min preincubation at various temperatures:Comparison of approximate cDNA yield reflecting enzyme stability after a 5-minute preincubation at various temperatures (Reaction conditions: 10-minute synthesis step at 55°C; 0.3 U/µL enzyme concentration; 500-base transcript). DBscript 2.0: Demonstrates outstanding resilience, retaining full cDNA yield even after a stringent 60°C preincubation, enabling higher reaction temperatures to ensure vastly improved sensitivity. DBscript Turbo: Delivers extreme thermal endurance, easily surviving 60°C preincubation with maximum yield and allowing for RT steps at 50–60°C even for longer, complex transcripts.

DBscript 2.0 and DBscript Turbo: Significantly faster protocols

Accelerated cDNA Synthesis Speed Comparison:Comparison of approximate cDNA yield between DIANA DBscript and Thermo SuperScript™ enzymes across 1-minute and 10-minute reaction times. Ultra-Fast Synthesis (1 min): In a rapid 1-minute reaction, DBscript 2.0 and DBscript Turbo operate >10x and >100x faster, respectively, than baseline SuperScript™ III, generating substantial yields before standard enzymes register significant activity. Maximum Yield (10 min): After a standard 10-minute incubation, the engineered DIANA mutants demonstrate profound dominance at elevated temperatures. At 60°C, both DBscript 2.0 and DBscript Turbo reach near-maximum yields (up to ~100%), drastically outperforming SuperScript™ IV and SuperScript™ III Flash.
