IsoFast™ Bst 1-Step Mix FAQs
Can IsoFast™ Bst 1-Step Mix be used at temperatures other than 65°C?
Yes, the enzyme is active between 57°C and 65°C. We do not recommend using it at temperatures outside this range as the activity will drop.
Can IsoFast™ Bst 1-Step Mix be heat inactivated?
Yes, both IsoFast™ Bst Polymerase and RTase Go can be inactivated by heating the tube at >80°C for 10 minutes.
Can IsoFast™ Bst 1-Step Mix be used for thermal cycle sequencing?
Unfortunately no, as the reaction temperatures are too high for enzyme stability.
Does IsoFast™ Bst Polymerase in IsoFast™ 1-Step Mix have reverse transcriptase activity?
Yes, but it is too low for use in reverse transcription applications. For some primer sets and targets IsoFast™ Bst Polymerase may be used as a single-enzyme (RT/DNA polymerase), but we recommend using the dedicated reverse transcriptase RTase Go as indicated.
Is IsoFast™ Bst 1-Step Mix supplied with dNTPs?
Yes. Both the buffer and the mix already contain dNTPs, so there is no need to order dNTPs separately.
What components are included in the IsoFast™ Bst 1-Step Mix kit?
The kit consists of the 2x IsoFast™ Bst Mix (including the amplification buffer, dNTPs, MgSO4, IsoFast™ Bst polymerase) and of RTase Go at concentrations optimized for reverse transcription isothermal amplification. The kit also contains one tube of 20x fluorescence dye that binds to dsDNA for real-time detection of products. The user only needs to add primers and target RNA.
