The number of bands in this product is 18. The 10bp DNA Ladder is ideal for determining the size of double-stranded DNA from 80 to 300 base pairs. The ladder consists of 23 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 l 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.
