Nucleic Acid Molecular Weight Markers
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 10bp DNA Step Ladder Molecular Weight Marker for Electrophoresis
Ten blunt-ended DNA fragments ranging from 10bp to 100bp in exactly 10bp increments
Promega Lambda DNA
Generates molecular weight size markers used in gel analysis of nucleic acids; nucleotide sequence has been determined.
Promega φX174 DNA/HinfI Markers Conventional DNA Digest Marker
This conventional DNA digest marker is generated by ΦX174 DNA digested to completion with HinfI to create 20 ethanol-precipitated DNA fragments ranging in size from 24bp to 726bp.
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 ΦX174, RF DNA
phiX174 replicative form (RF) is a double-stranded circular DNA molecule of 5,386 bases. Used in assays of restriction enzymes for the presence of nickase activity.
