General description
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.
Application
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.[1]
Other Notes
For optimal resolution, the recommended agarose gel concentration is 0.75%.
Sigma′s 1kb Ladder is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

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).
