Biomarkers are optimal for reading DNA fragments ranging from 50 to 10000 bp. They are stable at room temperature and are supplied dephosphorylated in order to allow labelling with polynucleotide kinase onto free 5’-termini.
Biotin and Rhodamine labelled biomarkers are available.These markers are evaluated for resolution, intensity and background on 7.5 % acrylamide and 3:1 SFAgarose: Agarose gels with ethidium bromide staining.
Biomarker High contains linear double-stranded DNA bands of 1000, 1500, 2000, 2500, 3000 bp. The concentration of each band is 50 ng/5 µl of Biomarker High applied.
