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.
These markers are evaluated for resolution, intensity and background on 7.5 % acrylamide and 3:1 SFAgarose: Agarose gels with ethidium bromide staining.
Biomarker EXT contains linear double-stranded DNA bands of 50, 100, 200, 300, 400, 500, 525, 700, 1000, 1500 and 2000 bp. The concentration of each band is 50 ng/5 µl of Biomarker EXT applied.
