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