SKU: DPT-500 Category: Tags: ,


DCSPol is a highly processive, thermostable DNA polymerase. Due to its genetic modifications DCSPol has an enhanced stability at room temperature with no activity loss for up to 1 month. The enzyme has 5’→3’ polymerization-dependent exonuclease replacement activity but lacks 3’→ 5’ exonuclease activity.

  • Suited for a wide range of PCR assays
  • TA cloning

Reagents Provided

  • DCSPol DNA Polymerase
  • 10 x Reaction buffer B (Mg2+ free) 0.8 M Tris-HCl, 0.2 M (NH4)2SO4, 0.2% w/v Tween-20
  • 10 x Reaction buffer BD (Mg2+ and detergent free) 0.8 M Tris-HCl, 0.2 M (NH4)2SO4
  • 25 mM MgCl2
  • 10 x Solution S
    • Additive that facilitates amplification of difficult templates (e.g. GC-rich DNA templates). This solution should be used at a defined working concentration (1x, 2x or 3x solution). Solution S is not a reaction buffer and should be used only if non-specific amplifications occur.


5 U/µl

Unit Definition

One unit is defined as the amount of enzyme required to catalyze the incorporation of 10 nmol of dNTPs into an acid-insoluble form in 30 minutes at 74ºC.

Storage and Dilution buffer

50% glycerol (v/v), 20 mM Tris-HCl pH 8.7 at 25ºC, 100 mM KCl, 0.1 mM EDTA and stabilizers.

Shipping and Storage conditions

Routine storage: -20ºC

Shipping and temporary storage for up to 1 month at room temperature has no detrimental effects on the quality of DCSPol DNA Polymerase.

Quality Control

The enzyme is free of nicking and priming activities, exonucleases and non-specific endonucleases. SDS/PAGE - 95 kD band, >98% pure. Activity and stability tested via thermo-cycling. The error rate per nucleotide per cycle is ~ 2.5 x 10-5; the accuracy is ~ 4 x 104. Estimated half life at 95ºC is 1.5 hours.
