Taq DNA polymerase in a glycerol-free storage buffer at a high concentration of 50 U/µL. Without glycerol it is well suited to lyophilisation, automated high-throughput workflows and any setup where small volumes must be pipetted accurately; the concentrated format is intended for bulk master mix production, robotic pipetting and lyophilised mixes for kits. It has 5'-3' polymerase and 5'-3' exonuclease activity, no proofreading activity, and leaves a 3' A overhang that is convenient for TA cloning.
Key features
Glycerol-free storage buffer, ideal for lyophilisation and automated dispensing.
50 U/µL to formulate concentrated master mixes with minimal enzyme volumes.
Retains about 90% of its activity after 50 freeze-thaw cycles.
Also incorporates dUTP and leaves a 3' A overhang for TA cloning.
Applications
- Lyophilisation of PCR master mixes
- Automated high-throughput testing
- Robotic pipetting
- Bulk kit and master mix manufacturing
- DNA target detection by PCR
- TA cloning and primer extension
