Zymo Research - DNA Molecular Weight Markers

The ZR DNA Markers™ are created as defined size fragments that encompass a range of sizes from 50 bp up to 10 kb. This makes DNA size approximation easy for both PCR products as well as plasmid DNAs. The ZR 50 bp DNA Marker™, ranging from 50 bp to 1200 bp, is well within the common range of PCR generated DNA fragments. For larger DNAs, the ZR 100 bp DNA Marker™ and ZR 1 kb DNA Marker™ are appropriate. Each marker comes with product information detailing the product and its application.

ZR 50 bp DNA Marker™

The 50 bp DNA marker consists of plasmid DNA that has been digested with endonucleases to yield 12 defined fragments that range in size from 50 - 1200 bp. The intensity of the 300 bp band is increased as an identifier.

ZR 100 bp DNA Marker™

The 100 bp DNA marker consists of plasmid DNA that has been digested with endonucleases to yield 12 defined fragments that range in size from 100 - 1500 bp. The intensity of the 500 and 1000 bp bands are increased as identifiers.
