Description

Bio-Star PCR-Mastermix (2×) HIGH-ROX for probes is developed for quantitative real-time PCR with fluorescent probes. The Mastermix contains all components, except template and primers, for successful PCR.

- The mix is optimized for efficient and reproducible hot-start real-time
   PCR of genomic, plasmid and viral DNA samples.

- The solution contains substances that increase half-life and
  processivity of DFS-Taq PLUS DNA polymerase blocked by MAB amd
  by enhancing its stability during PCR.

- It includes components that influence primer annealing temperature
  and characteristics of template melting thus enabling to increase the
  specificity of PCR and use templates with complicated structure.

- DFS-Taq Plus DNA polymerase is inactive at room temperature
  because of monoclonal antibodies.
