LAMDA BIOTECH INC 100bp DNA Ladder
100bp DNA Ladder consists of 11 DNA fragments ranging in size from 100-1500 base pairs (bp). 6µl will yield at least 30ng DNA in any single band. The intensity of the 500bp band has been increased to serve as a reference for easy identification. . This ladder can also be used side by side with the 100bp-50 DNA Ladder (Cat. No. M109) for more accurate estimation of the size your DNA fragments.
Biochain Institute Inc 100 bp DNA Ladder Plus, loading dye included, 250 ug, 0.5 ug per lane, 500 lanes/PK
BioChain provides a series of molecular weight markers, including DNA markers, RNA markers, and protein markers, to accurately determine the size of your DNA, RNA, and protein on the separation gels.
New England Biolabs, Inc. Lambda DNA-Hind III Digest – 1.5 ml
The HindIII digest of lambda DNA (cI857ind1 Sam 7) yields 8 fragments suitable for use as molecular weight standards for agarose gel electrophoresis. The approximate mass of DNA in each of the bands is provided (assuming a 1.0 ug load) for approximating the mass of DNA in comparably intense samples of similar size. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.
New England Biolabs, Inc. 100 bp DNA Ladder – 0.1 ml
A number of proprietary plasmids 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 points. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS. NEB also offers a Quick-Load version of this ladder with purple dye.
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. PhiX174 DNA-Hae III Digest – 0.05 ml
The HaeIII digest of X174 yields 11 fragments suitable for use as molecular weight standards for agarose gel electrophoresis. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.

Gold Biotechnology Inc 1 kb DNA Ladder 500 µL
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. This ladder is ready-to-use, and premixed with loading buffer dye for direct loading on gel.
