New England Biolabs, Inc. Quick-Load 100 bp DNA Ladder – 3.75 ml
Quick-Load 100 bp DNA Ladder is a pre-mixed, ready-to-load molecular weight marker containing bromophenol blue as a tracking dye. The 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 100-1,517 base pairs. The 500 and 1,000 base pair bands have increased intensity to serve as reference bands. NEB also offers a Quick-Load version of this ladder with purple dye.
New England Biolabs, Inc. Quick-Load Purple Low Molecular Weight DNA Ladder – 1.25 ml
Quick-Load Purple Low Molecular Weight 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. The DNA Ladder consists of a proprietary plasmid which is digested to completion with appropriate restriction enzymes to yield 11 bands suitable for use as molecular weight standards for agarose 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.
New England Biolabs, Inc. Fast DNA Ladder – 1 ml
The Fast DNA ladder is a pre-mixed, ready-to-load molecular weight marker containing xylene cyanol FF dye as a tracking dye. The DNA Ladder consists of proprietary plasmids, which are digested to completion with appropriate restriction enzymes to yield 11 bands suitable for use as molecular weight standards for fast electrophoresis systems as well as standard electrophoresis. The digested DNA includes fragments ranging from 50 base pairs to 10 kilobases. The 1 kb fragment has increased intensity to serve as reference band. This DNA Ladder has been tested and is suitable for use with many fast electrophoresis systems, such as the FlashGel DNA System from Lonza or the E-Gel Precast Agarose Electrophoresis System from Invitrogen.
New England Biolabs, Inc. Quick-Load 1 kb DNA Ladder – 3.75 ml
Quick-Load 1 kb DNA Ladder is a premixed, ready-to-load molecular weight marker containing bromophenol blue as a tracking dye. The DNA Ladder consists of proprietary plasmids which are digested to completion with appropriate restriction enzymes to yield 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 0.5-10.0 kilobases. The 3.0 kb fragment has increased intensity to serve as reference bands. NEB also offers a Quick-Load version of this ladder with purple dye.
Midwest Scientific 100bp DNA Ladder RTU (Ready-to-Use), 100bp
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 (0.5µg a load) for approximating the mass of DNA in comparably intense samples of similar size.
