Estimation of the size of DNA fragment generated by PCR is usually based on comparison of electrophoretic migration of the fragment with migration of DNA fragments of defined size (DNA markers). Size of PCR amplicons is often in range of 200 - 1500 bp. This region is covered by DNA fragments which are present in DNA markers.  Top-Bio produces three types of DNA markers with different sizes, uncoloured or coloured.
