Molecular Staging

Molecular Staging is addressing this demand with a portfolio of products and services based on technologies that are transforming the detection and measurement of both proteins and nucleic acids.

  • Most amplified strands are converted to double-stranded DNA at end of reaction.

  • MDA is a molecular amplification method that enhances simple, rapid, isothermal whole-genome amplification.

    By applying MDA to linear genomic DNA, it is possible to achieve a million-fold amplification with a very high degree of accuracy (bias 2-3 fold and greater than 99% coverage).

    Hexamer primers are added to linear genomic DNA together with a highly specialized polymerase. The unique properties of the polymerase proceed to carry out strand displacement DNA synthesis on double- or single-stranded DNA templates. Once initial priming has occurred, an exponential cascade of branched amplification generates single-stranded templates for ongoing priming.

    Comments Off on MDA Technology Overview
  • Multiple Displacement Amplification (MDA) is a proprietary amplification technology that enables the first effective whole genome amplification method.

    MDA enables for the first time:

    Whole Genome Amplification with enhanced coverage and minimal bias.

    The growing trend to study disease and drug response at the molecular level has focused attention on DNA as a precious resource. MDA technology enables the first effective, whole genome amplification method (W.G.A.) with the potential to transform the current practice of sample preparation and sample archiving for genetic testing.
