Nucleic Acid Molecular Weight Markers
Promega Lambda DNA/EcoRI + HindIII Conventional DNA Digest Marker
Created by digesting lambda DNA to completion with EcoRI and HindIII to generate 13 fragments of 125-21,226bp.
Promega Lambda DNA/EcoRI Conventional DNA Digest Marker
Generated by digesting lambda DNA to completion with EcoRI, resulting in six DNA fragments of 3,530-21,226bp.
Promega RNA Markers
RNA Markers consist of a ladder of 9 RNA transcripts synthesized in vitro from specific templates. Sizes: 281, 623, 955, 1,383, 1,908, 2,604, 3,638, 4,981 and 6,583 bases.
Promega pGEM™ Conventional DNA Digest Marker
Fifteen phenol-extracted, ethanol-precipitated DNA fragments ranging in size from 36bp to 2,645bp. These markers are generated from separate digests of pGEM(R)-3 Vector DNA with HinfI, RsaI and AvaII and then combined.
Promega 100bp DNA Step Ladder Molecular Weight Marker for Electrophoresis
Forty blunt-ended DNA fragments ranging from 100bp to 4,000bp in 100bp increments.
Promega 1kb DNA Step Ladder Molecular Weight Marker for Electrophoresis
Ten blunt-ended DNA fragments ranging from 1kb to 10kb in 1kb increments.
Promega 100bp DNA Ladder Molecular Weight Marker
11 fragments from 100bp to 1,000bp in 100bp increments and includes an additional 1.5kb band
Promega 25bp DNA Step Ladder Molecular Weight Marker for Electrophoresis
Twelve DNA fragments ranging from 25bp to 300bp in 25bp increments includes a visible 1,800bp backbone fragment.
Promega 200bp DNA Step Ladder Molecular Weight Marker for Electrophoresis
Thirty-three blunt-ended DNA fragments ranging from 200bp to 6,600bp in 200bp increments. The 1,000bp band appears more intense than all other bands.
Promega Lambda DNA/HindIII Conventional DNA Digest Marker
Generated by digesting lambda DNA to completion with HindIII, resulting in DNA fragments of 125-23,130bp.
Promega φX174 DNA/HaeIII Conventional DNA Digest Marker
Eleven phenol-extracted, ethanol-precipitated DNA fragments ranging in size from 72bp to 1,353bp.
