20 Base Pair DNA Ladder

20 bp ladder

3% Metaphor gel stained with ethidium bromide, shows bands from 20 bp to 500 bp. Bands are sharper on polyacrylamide gels.

Catalog Number: L-100
Price: $150
Description: 20 bp DNA ladder, 250 loadings

Inexpensive: 60 cents per loading, the least expensive in the industry

25 Blunt Ended Bands from 20 bp to 500 bp in 20 bp increments. Blunt ended bands avoid gel artifacts caused by fragment reannealing. Both polyacrylamide gel electrophoresis and a 3% Metaphor gel resolve bands from 20 bp to 500 bp. All bands on polyacrylamide are very sharp. The lower bands on the Metaphor gel will appear slightly diffuse due to the poorer resolving capability of Metaphor for very small fragments. Polyacrylamide gels provide 250 loadings per tube, Metaphor gels provide 125 loadings per tube.

High Intensity Band at 100 bp for easy band identification

Ideal for PCR products for accurately sizing small DNA products and small sized restriction digests

Supplied as a 500 ul stock solution in TE buffer, which is sufficient for 250 loadings for polyacrylamide gels or 125 loadings for Metaphor gels. An additional tube, labeled as "Working Solution", is supplied for making convenient instant use working solutions. The enclosed product information sheet instructs how to mix the working solution.
