Articles

Markers and Ladders for Gel Electrophoresis

We offers a variety of markers that aid size determination of samples separated by agarose and/or polyacrylamide gel electrophoresis. These products include markers for DNA, PCR fragments and RNA and can be concurrently run with the samples. All the markers stain well with common nucleic acid stains.

Protocols

Antibody-Enzyme Mediated Hot Start PCR Protocol

When using hot start Taq DNA polymerase, the enzyme remains inactive until heated. Hot Start DNA polymerase control is achieved by chemical or antibody modification of the enzyme.

End-Point PCR: Antibody-Mediated Hot Start PCR Protocol with Enhanced Specificity and Yield

Protocol using antibody mediated hot start polymerase. Method has short activation period (<1min), and results in higher yields and more specificity over standard PCR methods.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
