the 10bp dna ladder is ideal for determining the size of double-stranded dna from 80 to 300 base pairs. The ladder consists of 18 linear double-stranded fragments. The 100bp and 200bp fragment are present at increased intensity to allow easy identification. All fragments are precisely quantified and mixed during the production. For 5 µl loading, all fragments except 100bp and 200bp are 40ng. The 100bp and 200bp fragment are 100ng. This ladder is pre-mixed with loading dye and is ready to use.
