Product Information

ROX® DNA Size Standards for Genetic Analyzers

Intended use

The Red-500 DNA Size Standard is a fluorescent labeled ultra-accurate internal size standard for the reproducible sizing of fragment analysis peaks during capillary electrophoresis and precise DNA fragment size comparisons between capillary electrophoresis runs.


The DNA Size Standard contains 16 Red dye-labeled, single-stranded fragments in the 35-500 nucleotides range with respective basepair lengths of 35, 50, 75, 100, 139, 150, 160, 200, 250, 300, 340, 350, 400, 450, 490 and 500 bp. Each of the DNA fragments is labeled with ROX® fluorophore, resulting in sharp red peaks under denaturing conditions.


The Red-500 DNA Size Standard is for use with five-dye or six-dye spectral calibration Genetic Analyzers, such as 3130, 3500/SeqStudio and 3730 Series. Designed for fragment analysis, it has been adapted on e.g. GeneScan™ DNA fragment analysis software, by using the same parameters as the GeneScan™ 500 ROX® Size Standard.


This size standard can be combined with fragments, labeled with the dyes FAM™, VIC®, NED™, PET® (DS-33 / Dye Set G5) or with FAM™, VIC™, NED™, SID™, TAZ™ (DS-36 / Dye Set J6).
