SpeedSTAR HS DNA Polymerase
SpeedSTAR HS DNA Polymerase is optimized for fast PCR and does not require specialized PCR equipment. With an extension rate as fast as 10 sec/kb (compared to 60 sec/kb with standard Taq DNA polymerase), SpeedSTAR DNA polymerase dramatically reduces total reaction time and can be used with standard PCR machines.
SpeedSTAR HS DNA Polymerase includes two optimized buffers, Fast Buffer I and II, to provide efficient amplification across a wide size range (up to 20 kb) with less optimization than other polymerases. The antibody-mediated hot-start formulation provides high specificity. A dNTP mixture also is supplied with the polymerase.
- Optimized for fast PCR: amplify a 2-kb fragment in as little as 30 minutes using a standard PCR machine
- Excellent efficiency: robust performance, comparable to high-yield polymerases
- Optimized buffers allow amplification of fragments up to 20 kb
- Fast PCR: reactions can be completed in two-thirds less time
- Amplification of large DNA fragments
Nicking, endonuclease, nor exonuclease activities are detected following incubation of 1 µg of supercoiled pBR322, 1 µg of lambda DNA, or 1 µg of lambda-Hind III digested with 10 units of SpeedSTAR DNA Polymerase for 1 hour at 74°C.
The majority of PCR products generated with SpeedSTAR DNA Polymerase will have 3'-A overhangs; therefore, amplification products can be directly cloned into T-vectors. It is also possible to clone amplification products into blunt-ended vectors following blunting and phosphorylation of product ends.

Speeding up forensic analysis—That's Good Science!
Researchers for the Royal Canadian Mounted Police looked to high-speed polymerases as a potential tool for sample analysis. SpeedSTAR HS polymerase brought their PCR processing time from four hours down to 26 minutes!Watch the video

"It worked with a fast protocol I have used for a new design of a thermal cycler. My goal is to make PCR as fast as possible to cut down the overall time of a reactions. I wonder if the SpeedSTAR will work well with real-time reaction in the presence of dyes."
