Description générale

Sigma′s DirectLoad™ 1 kb Ladder contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb, and 2 kb repeats from 6 to 10 kb. For NA electrophoresis, 5 ul of the marker can be loaded directly into a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting.

Application

Suitable for size determination of dsDNA by DNA electrophoresis with either agarose or polyacrylamide gels.

The genetic dissection of physiological and pathological traits in laboratory model organisms is accelerated by the ability to engineer loss-of-function mutations at investigator-specified loci. This chapter describes the use of zinc-finger nucleases (ZFNs) for the targeted disruption of endogenous rat

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.

Protocoles

End Point PCR Protocol for Long and Accurate DNA Amplification

Protocol for high fidelity amplification of long PCR fragments up to 22kb from complex DNA mixtures and up to 40kb from simple DNA mixtures.

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.

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.
