Bst Polymerase | Bst DNA polymerase
● Product Name: Magigen Bst DNA polymerase / Bst Polymerase, Large Fragment
● Catalog#: D001M
● Size: 16000U
● Bst Polymerase Price: 355 USD
● Contents
Composition Vol
10×Reaction Buffer 6*1 1ml×1
Bst DNA Polymerase, Large Fragment 500µl（8U/µl）
100mM MgSO4*2 1ml×2
*1. Contains 20mM MgSO4;
*2. The recommended final concentration is 8mM, which can be adjusted as needed.
● Advantages and Features
Magigen Bst DNA Polymerase, Large Fragment, is the portion of the Bacillus stearothermophilus DNA Polymerase protein that contains the
5´ → 3´ polymerase activity and strong strand displacement activity, but lacks 5´ →3´ exonuclease activity. Bst could be used for isothermal amplification reactions, such as LAMP (Loop-mediatedisothermal amplification)，RCA (Rolling-circle amplification), etc.
● Storage Conditions and Shelf Life
Stored at -20 ℃ for 12 months
● Application
1. Random primer labeling;
2. Synthesis of the second strand cDNA;
3. Tailing of single dA;
4. DNA strand displacement synthesis.
● Unit Definition
One unit is defined as the amount of enzyme that will incorporate 10 nmol of dNTP into acid insoluble material in 30 minutes at 37°C
● How to use Bst polymerase
Taking LAMP amplification as an example:
Configure the reaction system according to the following table:
Composition Vol
10×Reaction Buffer 6 2.5 µL
100mM MgSO4 1.5 µL
10mM dNTP 3.5 µL
FIP/BIP Primers(10μM) 4 µL
F3/B3 Primers(10μM) 2µL
LoopF/LoopB Primers(10μM) 2 µL
Bst DNA Polymerase, Large Fragment 1 µL
template DNA >10 copies
Total 25 µL
Incubate at a constant temperature of 60 ° C-65 ° C for 45-60 minutes.
● Cautions
a. The combination and amount of amplification primers can be optimized and adjusted according to the actual situation. It is recommended that the reaction time should not exceed 60min.
b. If fluorescence detection is used, additional nucleic acid dye shall be added.
c. If the additional physiological saline content added to the overall system exceeds 10 μl, Amplification will not proceed normally, and it is necessary to increase the usage of Bst enzyme.
● Note
Magigen MagicScript Bsu DNA polymerase is a qualified enzyme with good price.
