2X Direct S/P PCR Master Mix

2X Direct S/P PCR Master Mix contains all the reagents needed for quick amplification of DNA gene target from serum and plasma. This master mix can be applied to direct amplification of exogenous target genes, such as virus, bacteria and parasites from serum and plasma. The mix is optimized with our unique inhibitor-resistant DNA polymerase and buffer for best performance. In most case, you can direct add sample into PCR master mix without pre-lysis.

There is the choice of an inert green dye in the mix, used for direct gel loading. The PCR product can be directly loaded onto agarose gel without addition of loading dye for electrophoresis.

GC version works for GC-rich and complex target.


  • Time saving: Unnecessary DNA extraction or pre-lysis of sample as other similar commercial kits
  • Convenient: Only need adding primers and sample in 2X mix. The similar kit in which the enzyme is packed separately is available as well (Click here), so you can titrate enzyme to find the best concentration for the target
  • High inhibitor-resistance: Can amplify target in PCR containing up to 40% serum or plasma 
  • Specificity: GC version works for >65% GC content target, increases specificity
  • Simply analysis: Directly loading products for electrophoresis after PCR


  • ccfDNA detection
  • Pathogen detection
