Special Application

SD Polymerase

SD Polymerase is a novel artificial thermostable polymerase providing a strong strand displacement activity. Unlike natural enzymes with strong strand displacement activity as Phi29 or Bst Polymerase, which are active below 68 °C only, SD Polymerase is stable up to 93 °C. This allows running isothermal amplification like LAMP with initial heating-up for increased specificity.
SD Polymerase has 5’ – 3’ polymerase and 5’ – 3’ strand displacement activities. It does not have any exonuclease activity. The enzyme does 3’-A-overhangs. SD Polymerase is also available as a HotStart version.

SD Polymerase is used in our WGA-Kit for whole genome amplifcation:  One Step WGA Kit


  • Available in high and low concentrations and as a HotStart version
  • Higher yields, speed and efficiency compared to Taq Polymerase
  • Suitable for amplification of short (100 bp) and long (20 – 30 kb) DNA fragments
  • Suitable for simple (e.g. plasmids) and complex (e.g. genomic DNA) templates


  • Suitable for different PCR methods, also long-range PCR
  • PCDR (Polymerase Chain Displacement Reaction)
  • Strand displacement like LAMP (Loop-mediated isothermal amplification)
