Hot Start DNA Polymerase

Bionexus offers you a comprehensive selection of affordable and high quality kits, enzymes, and reagents to support all your amplification needs.

Hot Start DNA Polymerase (5 units/ul)

  • Set up time is significantly reduced.
  • Reduces the formation of non-specific products
  • Improves results from multiplex reactions
  • Essential for low copy number

Bionexus Hot Start DNA Polymerase is a modified form of Bionexus Taq DNA Polymerase that is activated at elevated temperatures. A chemical moiety is attached to the enzyme at the active site and renders it inactive at room temperature. This feature prevents mispriming during setup and the first ramp of thermal cycling, resulting is higher specificity and greater yields. The chemical moiety is cleaved during a 15 minute heat activation step, releasing the active Hot Start Taq DNA Polymerase into the reaction.

Amplification with Bionexus Hot Start Polymerase

Bionexus Hot Start Polymerase was used to amplify a 610 bp genomic DNA sequence. Two different buffers are included with Hot Start Taq: a standard Ammonium Buffer suitable for most applications, and a buffer with a balanced Ammonium/Potassium concentration which has been shown to improve results with more complicated PCR systems such as multiplex PCR. Amplification results using each buffer are shown.
