ABclonal Technology 100 bp DNA Ladder
The 100 bp DNA Ladder is a ready-to-use DNA Ladder, which is pre-mixed with loading dye for direct gelloading. This product consists of 11 individual DNA fragments: 100 bp, 200 bp, 300 bp, 400 bp, 500 bp, 600 bp, 700 bp, 800 bp, 900 bp, 1000 bp and 1500 bp, derived from amixture of PCR products and specifically digested plasmid DNA. The 500 bp fragment is present at increased intensity for easy identification.
New England Biolabs, Inc. TriDye™ 1 kb Plus DNA Ladder – 1.25 ml
TriDye 1 kb Plus DNA Ladder is a pre-mixed, ready-to-load molecular weight marker containing 3 dyes which serve as visual aids to monitor the progress of migration during agarose gel electrophoresis. The 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. This 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 points.

STEMCELL Technologies DNA Loading Dye, Size: 3 mL
DNA Loading Dye is a ready-to-use marker dye containing orange G (0.4%), bromophenol blue (0.03%), and xylene cyanol FF (0.03%), in 15% Ficoll 400, 10 mM Tris-HCl (pH 7.5), and 50 mM EDTA (pH 8.0). The dye is used for loading DNA samples into agarose gel wells and tracking migration during electrophoresis. In a 0.5 - 1.4% agarose gel in 0.5X TBE, xylene cyanol FF migrates at approximately 4 kb, bromophenol blue at approximately 300 bp, and orange G at approximately 50 bp. This product is free of nuclease activity.
New England Biolabs, Inc. Quick-Load Purple 100 bp DNA Ladder – 3.75 ml
Quick-Load Purple 100 bp DNA Ladder is a pre-mixed, ready-to-load molecular weight DNA marker containing one tracking dye. Tracking dye does not leave a shadow under UV light. Quick-Load Purple 100 bp DNA Ladder consists of proprietary plasmids, which are digested to completion with appropriate restriction enzymes to yield 12 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 100 bp to 1,517 bp. The 500 and 1,000 bp bands have increased intensity to serve as reference bands.
