100 - 1000 Ladder 100-1000 bp DNA ladder marker of molecular size, in addition to containing two dyes, allowing for visual observation of the migration of DNA molecules during electrophoresis. DNA ladder consists of fragments of a strictly defined size from 100 to 1000 base pairs. A fragment size of 500 bp is clearly marked to facilitate identification. All fragments are blunt ended. The length of DNA fragments and the mass of DNA: 100, 200, 300, 400, 500 - double the number, 600, 700, 800, 900; 1000 Concentration: 0.1 µg Quantity: 500 µl Storage: Marker is stable at room temperature. For longer term storage we recommend -20 ° C Usage: Generally it is recommended to apply 1 µl of DNA size standard per each 1 mm width of comb/well. Usually 2 µl do 5 µl per line.
