PCR Molecular Size Marker contains a mixture of eight defined DNA fragments ranging from 50 to 2000 bp at convenient size intervals for characterising small DNA products. The markers are supplied in gel loading buffer containing two tracking dyes that do not interfere with UV illumination of ethidium bromide-stained bands. A separate vial of 6X Loading Buffer is included. Each vial of markers is sufficient for 50 lanes on TBE or TAE agarose stained with ethidium bromide. The recommended amount for loading (5 µl) produces bands of even intensity that are bright, sharp and easy to photograph.

Product comprises:
250 µl PCR marker in 1X loading buffer
1 ml 6X loading buffer containing Orange G, Xylene Cyanole FF and glycerol
