14 DNA fragments: 100, 200, 300, 400, 500x2, 600, 700, 800, 900 and 1000x2, 1200, 1500, 2000, 3000bp: 100-3000bp DNA Marker, ready-to use, contains a mix of 14 individual DNA fragments (in base pairs): 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000, 1200, 1500, 2000, 3000bp.
The intensities of the bands of 500bp, 1000bp are increased to yield internal reference indicators.
