    Lyophilizing reagents: requirements, challenges, and considerations for assay developers



Bst 3.0 DNA Polymerase is an in silico designed homologue of Bacillus stearothermophilus DNA Polymerase I, Large Fragment engineered and fused to a novel nucleic acid binding domain for improved isothermal amplification performance and increased reverse transcription activity. Bst 3.0 DNA Polymerase contains 5´→3´ DNA polymerase activity with either DNA or RNA templates and strong strand displacement activity, but lacks 5´→3´ and 3´→5´ exonuclease activity. Bst 3.0 DNA Polymerase demonstrates robust performance even in high concentrations of amplification inhibitors, including dUTP and features significantly increased reverse transcriptase activity compared to Bst DNA Polymerase.

An example of the utility and speed offered by Bst 3.0 DNA Polymerase can be seen in this publication that explores the development of a novel digital LAMP assay: Rapid pathogen-specific phenotypic antibiotic susceptibility testing using digital LAMP quantification in clinical samples.

Fast, single-enzyme RT-LAMP can be performed using Bst 3.0 
RT-LAMP was performed using indicated DNA polymerase and Jurkat total RNA and primers for two genes (ACTB, left; HMBS2, right). Fastest results were observed with a 2-enzyme system, Bst 2.0® and WarmStart RTx, but robust amplification was also observed using Bst 3.0 without additional RT. Bst LF, Bst 2.0 and competitor enzymes showed highly variable performance, with slow threshold times or reaction failure on one of the two targets.
