DNA Ladders

A unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products to yield 13 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 250-10,000 base pairs. The 1K and 3K bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

The 1 kb PLUS™ is composed of 14 individual DNA fragments: 25K, 10K, 8K, 6K, 5K, 4K, 3K, 2.5K, 2K, 1500, 1000, 750, 500, 250 base pairs. This product contains two enhanced bands (3K and 1K bp) for easy reference. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 11 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 100-1,500 base pairs. The 500 and 1,500 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples of similar size. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 12 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 100-3,000 base pairs. The 500 and 1,500 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples of similar size.The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 17 fragments, suitable for gel electrophoresis. The DNA includes fragments ranging from 50-1,500 base pairs. The 200 and 500 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 g a load) for approximating the mass of DNA in comparably intense samples of a similar size.The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

GoldBio's SuperLadder (50 bp-25 kb) is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA Ladder is composed of 26 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1.2k, 1k, 900, 800, 700, 600, 500, 450, 400, 350, 300, 250, 200, 150, 100 and 50 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA.

This product contains four enhanced bands (3k, 1.2k, 500 and 200 bp) for easier reference. In addition, three tracking dyes are present (Xylene cyanol FF, Bromophenol blue and Orange G) which mimic the migration of 4,000 bp, 500 bp and 50 bp dsDNA respectively during electrophoresis on a 1% TAE agarose gel which helps in real time monitoring.
