The 200 bp DNA Ladder consists of twelve double-stranded DNA bands that are suitable as molecular weight standards for agarose gel electrophoresis.

The product is ready-to-use; it is premixed with 1× Loading Buffer for direct loading 3~6 μl on agarose gel electrophoresis.

The ladder is composed of twelve individual DNA fragments (in base pairs): 4000, 2200, 2000, 1800, 1600, 1400, 1200, 1000, 800, 600, 400 and 200 bp. It contains one intense band (1000 bp) for easy orientation. To load 6 μl of the product will provide 50 ng per DNA fragment with one intense fragment of 100 ng at 1000 bp.
