Abbexa's Heat-Activated DNA Polymerase is a heat-activated thermostable enzyme with improved specificity as compared to standard polymerases, by eliminating all non-specific priming and the formation of primer-dimers. It is inactive at room temperature, allowing for reaction set-up at room temperature, and therefore requires activation by heat treatment for 10 minutes prior to PCR cycling. The enzyme is available as ready-to-use 2X reaction mixes: abx461025, abx461026.

Target	Heat-Activated DNA Polymerase
Tested Applications	PCR
Form	Liquid
Biological Activity	One unit is defined as the amount of enzyme that incorporates 10 nmol of dNTPs into acid-insoluble form in 30 minutes at 72 °C.
Storage	Store all components at -20°C. It is not recommended to store the enzyme at -80°C as ice crystals may form on the active site, which can affect the enzyme activity. Avoid repeated freeze/thaw cycles.
Shelf Life	Up to 12 months.
Buffer	The exact formulation is proprietary.

Availability	Shipped within 10-20 working days.
Note	THIS PRODUCT IS FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC, THERAPEUTIC OR COSMETIC PROCEDURES. NOT FOR HUMAN OR ANIMAL CONSUMPTION.
Directions for use	Reaction Components: Component Volume Template and Primers Variable, as required 50 mM MgCl2 Solution 3 µl 10X NH4 Reaction Buffer 5 µl 100 mM dNTP Mix (abx461012) 0.5 µl Heat-Activated DNA Polymerase 1 µl Water Variable, up to 50 µl Total Volume 50 µl Thermal Cycling Conditions: Activation: pre-heat at 95 °C for 10 minutes Denaturation: 94-96 °C Annealing: dependent on primer Tm Extension: 72 °C, allowing 15-30 seconds per kb Notes: Pre-incubate at 95 °C for 10 minutes to activate the enzyme. Subsequently, the reaction can be treated according to the end user's existing protocol. If extension time exceeds 2.5 minutes, a maximum of 30 cycles should be used. Increasing the number of cycles may lead to smearing when run on an agarose gel. The optimal conditions will vary from reaction to reaction and are dependent on the system used. Each parameter needs to be adjusted by the end user and some optimization may be required. The optimal final Mg2+ concentration is likely to be in the region of 1.5 - 2.5 mM. It is recommended to use at least 1 U of Heat-Activated DNA Polymerase per 50 µl reaction volume.
