Bst X DNA Polymerase is a thermostable DNA polymerase from Geobacillus, homologous to the DNA polymerase from Bacillus stearothermophilus (Bst). Bst X lacks 5’→3′ and 3’→5′ exonuclease activity and exhibits a stronger strand-displacement activity than Manta 1.0 DNA Polymerase that may allow it to perform better in isothermal amplification technologies.

Usage Notes:

• Optimal reaction temperature from 60-70°C.
• Heat inactivated at 80°C after 10 min incubation.
• High Tolerance to the non-ionic detergents Tween-20, Tween-80, TX-100, and NP-40 (up to 5% final concentration).
• Active in salt from 40 to 125 mM.

Buffer Description10x Bst X Xcelerator Reaction Buffer, contains 2 mM MgSO₄ at 1X concentration. Depending on the application, it may be necessary to adjust the MgSO₄ from 2-10 mM final concentration.

Source of ProteinA recombinant E.coli strain carrying the Bst X DNA Polymerase (exo-) polymerase gene.
