Nucleic Acid Molecular Weight Markers
Sigma Aldrich Fine Chemicals Biosciences 1 kb DNA Ladder for DNA el
Sigmas 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 mul 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(R) Green and Nancy-520.

New England Biolabs, Inc. Quick-Load Purple 1 kb Plus DNA Ladder – 3.75 ml
Quick-Load Purple 1 kb Plus DNA Ladder is a pre-mixed, ready-to-load molecular weight marker containing one tracking dye. Tracking dye does not leave a shadow under UV light. Quick-Load Purple 1 kb Plus DNA Ladder consists of proprietary plasmids, which are digested to completion with appropriate restriction enzymes to yield 19 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 100 bp to 10 kb. The 0.5, 1.0 and 3.0 kb bands have increased intensity to serve as reference bands.
Sigma Aldrich Fine Chemicals Biosciences PCR 100 bp Low Ladder for
Sigmas PCR 100 bp Low Marker contains 10 dsDNA fragments from 100 - 1 000 bases evenly spaced in 100 bp repeats. Two ul of the ladder should be diluted in gel loading buffer and then loaded in a single lane on an agarose gel.
LAMDA BIOTECH INC 100bp DNA Ladder
100bp DNA Ladder consists of 11 DNA fragments ranging in size from 100-1500 base pairs (bp). 6µl will yield at least 30ng DNA in any single band. The intensity of the 500bp band has been increased to serve as a reference for easy identification. . This ladder can also be used side by side with the 100bp-50 DNA Ladder (Cat. No. M109) for more accurate estimation of the size your DNA fragments.
Enzo Life Sciences AMPIGENE DNA Ladder 250-10,000 bp (100lanes)
AMPIGENE DNA Ladder 250-10,000 bp contains DNA fragments ranging from 250bp to 10,000bp that can be used as molecular weight standards for agarose gel electrophoresis. The bands are evenly spaced and are intensified at 1,000bp and 3,000bp to serve as easily identifiable reference bands. The approximate mass of DNA in each of the bands is provided, assuming 5µl load, for determining the approximate mass of DNA in samples with comparable intensity and size. Long Term Storage: -20°C.
Zymo Research Corporation ZR 100 bp DNA Marker™ (50 μg / 100 μl)
