How much ladder do I add to gel?
How much ladder do I add to gel?
For a standard electrophoresis system, we recommend loading 0.5 µg (20 µl) of the Fast DNA Ladder on the agarose gel. For a fast electrophoresis system (5 to 30 minutes separation), follow the system’s manufacturer recommendations: 5 to 20 µl load.
How much loading Dye to add to DNA ladder?
The recommended loading volume of the 1 kb DNA ladder is 6 μL per lane. DNA Loading Dye is a ready-to-use marker dye containing orange G (0.4%), bromophenol blue (0.03%), and xylene cyanol FF (0.03%), in 15% Ficoll® 400, 10 mM Tris-HCl (pH 7.5), and 50 mM EDTA (pH 8.0).
How do you dilute 100 bp DNA ladder?
This ladder is preferred by our lab because of its broad range (100 bp to 10,000 bp) and even intervals. Its stock concentration is 1 µg/µl of DNA. The ladder is diluted to a 1:4 solution in water for use (3 parts water for 1 part ladder). To make 100 µl, 75 µl of water are combined with 25 µl of the DNA ladder.
How much DNA is needed for gel electrophoresis?
The minimum detectable amount of DNA using ethidium bromide is 1 ng. 10ul of you sample (with 3-5ng/ul ) will be more than enough to be visualized on the gel. About 25 ng of DNA will give excellent results on agarose gel.
Do DNA ladders need loading dye?
Ladders are ready to use and suitable not only for DNA sizing but also for approximate DNA quantification in gels. Every ready-to-use ladder is supplied with the nuclease-free Loading Dye Solution, which ensures optimal migration and quantification of your DNA probes.
Why is DNA ladder used?
A DNA ladder is a solution of DNA molecules of different lengths used in agarose or acrylamide gel electrophoresis. It is applied as a reference to estimate the size of unknown DNA molecules that were separated based on their mobility in an electrical field through the gel.
What is 1 KB plus DNA ladder used for?
Thermo Scientific GeneRuler 1 kb Plus DNA Ladder is recommended for sizing and approximate quantification of a double-stranded DNA in the range of 75 bp to 20,000 bp on agarose gels. The DNA ladder consists of 15 DNA fragments and is provided with 6X TriTrack DNA Loading Dye. Highlights of 1 kb Plus DNA Ladder.
