How much 100 bp Ladder to Load?
10 μl
We recommend loading 10 μl (0.5 μg) of Quick-Load 100 bp DNA Ladder per gel lane. In general, it is recommended to load 1µl per mm of gel lane.
What is a 100 bp DNA Ladder?
Invitrogen 100 bp DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA in the range of 100 bp to 2,000 bp. 100 bp DNA Ladder consists of 13 individual chromatography-purified DNA fragments and has reference bands at 2000, 1500, and 600 bp for easy orientation.
How do you make a 100 bp DNA Ladder?
To make 100 µl, 75 µl of water are combined with 25 µl of the DNA ladder. Then, 20 µl of 6X loading dye is added and the solution is split into 60 µl aliquots (0.5 ml microcentrifuge tubes) and stored at -20 C.
How do I choose a DNA Ladder?
The most important factor in choosing a DNA ladder is the expected size of the DNA bands in your experiment. You want to make sure that the range of the DNA ladder, from its smallest to its largest fragment, includes the expected size of the DNA fragments you are testing (Figure 1).
What is RNA ladder?
RNA ladders consist of RNA fragments for sizing single-stranded RNA in glyoxal or formaldehyde agarose gels. We supply a wide range of RNA ladders for accurate size and mass estimations (quantitation) of RNA transcripts from 0.1 to 10 kb.
How much DNA do you need to load?
How much DNA should be loaded per well of an agarose gel? The amount of DNA to load per well is variable. The least amount of DNA that can be detected with ethidum bromide is 10 ng. DNA amounts of up to 100 ng per well will result in a sharp, clean band on an ethidium bromide stained gel.
What is a 50 bp ladder?
50 bp DNA Ladder consists of 10 DNA fragments ranging from 50 bp to 500 bp and is supplied in ready-to-use format containing an orange tracking dye. It allows sizing and concentration estimate of DNA fragments on agarose gels generated by PCR or restriction digest.
Why is it called a 1 kb ladder?
b. 1 kb plus DNA ladder is a DNA size standard consisting of DNA fragments of length ranging from 0.5 kb to 10 kb used for the determination of the size of double-stranded DNA fragments of length ranging from 250 bp to 25,000 bp. 1 kb plus DNA ladder consists of 14 individual chromatography-purified DNA fragments.
How much do you load on gel?
Standard gel combs
| Recommended loading volume* | ||
|---|---|---|
| Well format | 1.0 mm thickness | 1.5 mm thickness |
| 10-well | 25 µL | 37 µL |
| 12-well | 20 µL | – |
| 15-well | 15 µL | 25 µL |
What is a PCR ladder?
PCR DNA Ladder is a convenient ready-to-use dsDNA ladder supplied in 0.5 ml packs for 250 lanes. It ranges from 100 – 3 000 bp and is mass-calibrated for easy DNA quantification.
How do you calculate DNA concentration in PCR?
DNA concentration is estimated by measuring the absorbance at 260nm, adjusting the A260 measurement for turbidity (measured by absorbance at 320nm), multiplying by the dilution factor, and using the relationship that an A260 of 1.0 = 50µg/ml pure dsDNA.
