FSTM Taq DNA polymerase is the latest generation Taq-based DNA polymerase. It possesses high amplification efficiency as does Taq polymerase, and fast elongation ability as does KOD polymerase, can be used in a variety of PCR. The FSTM PCR Buffer, designed for FSTM Taq DNA polymerase, can be used in fast amplification reaction. The elongation rate of FSTM Taq DNA polymerase is as fast as 5s/kb for simple templates, which shortens the amplification time at least by half .

Unit Definition
One unit is defined as the amount of the enzyme required to catalyze the incorporation of 10 nM of dNTPs into an acid-insoluble form in 30 minutes at 70°C using hering sperm DNA as substrate.
Quality Control
The absence of endodeoxyribonucleases, exodeoxyribonucleases and ribonucleases is confirmed by appropriate quality tests

-
Gently vortex the sample and briefly centrifuge to collect all drops to the bottom of the tube.
·Overlay the sample with mineral oil or add an appropriate amount of wax. This step may be omitted if the thermal cycler is equipped with a heated lid.
·Place samples in a thermocycler and start the program.
