Allgemeine Beschreibung

Sigma′s 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. In nucleic acid gel electrophoresis, five μl of the marker should be diluted in gel loading buffer and then loaded in a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting. All DNA markers can be stained with ethidium bromide, SYBR® Green, and Nancy-520.

Anwendung

1 kb DNA Ladder has been used as a molecular marker to determine the molecular weight and size of double stranded DNA during gel electrophoresis.

Komponenten

Sigma′s 1kb Ladder is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

Sonstige Hinweise

For optimal resolution, the recommended agarose gel concentration is 0.75%.

One mononuclear and another dinuclear Pd(II) complexes bearing a α-N-heterocyclic thiosemicarbazone ligand have been synthesized, fully characterized and studied as biological agents. In both complexes, the palladium center is coordinated to 3,5-diacetyl-1,2,4-triazol bis(N4,N4-dimethylthiosemicarbazone) via three sites (N, N and S).

Gel Electrophoresis Markers

Markers for gel electrophoresis aid size determination of DNA, PCR fragments, and RNA, staining well with common nucleic acid stains.

Selecting DNA, RNA, and PCR Fragment Markers and Ladders for Gel Electrophoresis

Choose the appropriate markers and ladders for nucleic acid size determination of samples separated by electrophoresis. Determine size of DNA, RNA and PCR-generated fragments using agarose or polyacrylamide gels.
