Product description

qPCR 2x SYTO-9 Master Mix is dedicated for more demanding qPCRs with quantification of the DNA amplicons with fluorescent DNA dye SYTO-9. This Master Mix is especially useful for amplification of larger DNA fragments (upto 1 kbp) and for demanding high resolution melting (HRM) analysis.

SYTO-9

  • The Mix contains fluorescent DNA dye SYTO-9, which after binding to double-stranded (ds)DNA becomes strongly fluorescent with maximal excitation at 485 nm and emission at 498 nm (green light). These spectral parameters are similar to those of SYBR green I (497/520 nm) and therefor the same filter set can be used. Because fluorescence of unbound SYTO-9 is very low, enhanced fluorescence corresponds to an increase in dsDNA amplicons produced during PCR.

Hot start

  • qPCR 2x SYTO-9 Master Mix contains anti-Taq DNA polymerase monoclonal antibody which inactivates enzymatic activity of the enzyme.  After the first denaturation cycle, the antibody is irreversibly inactivated and Taq DNA polymerase regains enzymatic activity.

Rapid samples preparation

  • All components of the qPCR 2x SYTO-9 Master Mix are 2x concentrated, which facilitates rapid preparation of the PCR samples. The samples are prepared by mixing an aliquot of the Mix with oligonucleotide primers, template DNA and H2O (included).
  • qPCR 2x SYTO-9 Master Mix is especially useful for routine analyses of large numbers of DNA samples. To 0.5 ml of the Master Mix in original tube, primers (e.g. 40 µl forward and 40 µl reverse), fluorescent probes and PCR H2O (upto 960 µl) are added and mixed; such "armed" Mix can be stored at -20 ± 5oC. Immediately before PCR, the Mix is thawed and each 24 µl aliquot is mixed with 1 µl of the tested DNA template.
