New England Biolabs, Inc. 50 bp DNA Ladder – 0.5 ml
A number of proprietary plasmids are digested to completion with appropriate restriction enzymes to yield 17 bands suitable for use as molecular weight standards for agarose and polyacrylamide gel electrophoresis. The digested DNA includes fragments ranging from 50-1,350 base pairs. The 200 and 500 base pair bands have increased intensity to serve as reference points. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.
New England Biolabs, Inc. Low Molecular Weight DNA Ladder – 0.5 ml
A proprietary plasmid is digested to completion with appropriate restriction enzymes to yield 11 bands suitable for use as molecular weight standards for both agarose and polyacrylamide gel electrophoresis. This digested DNA includes fragments ranging from 25-766 base pairs. The 200 base pair band has increased intensity to serve as a reference point. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.
