For size estimation of megabase DNA separated by pulsed field gel (PFG) electrophoresis, Lonza offers 2 DNA standards in InCert™ Agarose Gel Plugs; Lambda DNA ladders and Saccharomyces cerevisiae chromosomal DNA.

These DNA standards are of consistent high quality. The agarose used to make the gel plugs is InCert™ Agarose, specifically developed and quality assured for preparation of chromosomal DNA in agarose gel plugs. InCert™ Agarose, having twice the gel strength of other low melting temperature agaroses, forms strong gel plugs which are easier to handle and cut. Like other Lonza Genetic Technology Grade™ Products, each lot of standard is tested and certified. The standards are quality assured to yield consistent molecular weights, sharp bands, and low background in pulsed field gel electrophoresis. A Certificate of Performance is included with each standard.

Lonza’s standard DNA Ladders are ready-to-dilute prior to loading on your gel. Plasmid-free to ensure minimal background. For all of Lonza’s Ladders, each band has an ideal 50% G-C content for rapid, precise sizing and sharp resolution. Our Ladders are free from contaminating plasmid DNA so they have minimal background, giving you the perfect gel the first time, every time.
