1 kb ladder plus is ideal for determining the size of double-stranded DNA from 100 to 10,000 base pairs. The ladder consists of 15 linear double-stranded fragments .The 500bp and 3,000bp fragment are present at increased intensity to allow easy identification. All fragments are precisely quantified and mixed during the production. For 5 ul loading, all fragments except 500bp and 3,000bp are 40ng. The 500bp and 3,000bp fragment are 100ng. This ladder is pre-mixed with loading dye and is ready to use.
Do not heat before loading.
For quantification, adjust the concentration of the sample to equalize
it approximately with the amount of DNA in the nearest band of the ladder.
Visualize DNA by staining with ethidium bromide or with SYBR® Green I.
