New England Biolabs, Inc. Quick-Load Purple 1 kb Plus DNA Ladder – 1.25 ml
Quick-Load Purple 1 kb Plus 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. Quick-Load Purple 1 kb Plus 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. The 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 bands.
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.
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.
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.
Alkali Scientific DNA Markers (Low Range) 250 bp Ladder, 1 Milliliter
DNA Markers (Low Range) 250 bp Ladder (1 mL) is a liquid format DNA marker used in gel electrophoresis for the molecular weight determination of DNA fragments. The 250 bp ladder contains a series of DNA fragments that are useful for estimating the size of unknown DNA samples. This marker is commonly used in molecular biology labs to confirm the integrity of DNA samples, analyze restriction enzyme digestions, and ensure accurate molecular size estimation during electrophoresis. The 250 bp ladder is ideal for low-range applications, making it a standard choice for small DNA fragment analysis and various molecular research experiments.
