Description

KOD SYBR® qPCR Mix is a highly efficient 2x Master Mix for real-time PCR using SYBR® Green I and based on the 3'→5' exonuclease deficient KOD DNA Polymerase. The master mix contains all the required components, except the ROX reference dye and primers (50x ROX reference dye is supplied separately with this kit). The master mix aids reaction setup, and improves the reproducibility of experiments.This product was optimized to be highly efficient and robust in the SYBR® Green assay.

This product is sold in U.S. under the license of US patent 7772383
from Chakrabarti Advanced Technology NewCo LLC.

Features

  • Quantitative analysis can be achieved using long targets, up to 2kb.
  • Efficient for GC-rich targets
  • Effective amplification can be achieved using crude samples.

    (Company A)

Target: IGF2R (189 bp / GC content: 83%)
Template: HeLa cDNA was synthesized using
Rever Tra Ace™ qPCR RT Kit (Code No. FSQ-101)
with total RNA from HeLa cells.

A real-time PCR assay was performed using primers for conventional PCR. KOD SYBR® qPCR Mix exhibited quantitative amplification. [ABI StepOnePlus™]

Example 2.Enable the effective amplification from crude samples.

Genotyping of knock-in mice using mouse-tail lysates. [ABI 7500 Fast]
Primers were designed so that the amplicons were 100 bp (Tm: 79 ºC) and 341 bp (Tm: 84 ºC) for wild-type and knock-in, respectively. All genotypes were successfully detected.

Template: Mouse tail lysate (alkaline lysis method)
Primer ratio: F: WT: KI: = 0.2: 0.2: 0.67 mM (final)
Sample: Mouse tail lysate 2 µL / 20 µL reaction

One-tube ASP-PCR analysis using whole blood specimen. [ABI 7500 Fast]

SNP analysis was performed with a GC tailed primer from whole blood samples using KOD SYBR® qPCR Mix. All types of SNP were successfully determined by KOD SYBR® qPCR Mix. No signal was detected using the Taq-based conventional master mix (data not shown).
