What is a 50 bp ladder?
Invitrogen 50 bp DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA in the range of 50 bp to 2,500 bp. 50 bp DNA Ladder consists of 17 individual chromatography-purified DNA fragments and has reference bands at 2500, 800, and 350 bp for easy orientation.
Are DNA ladders double-stranded?
Invitrogen DNA ladders are composed of double-stranded DNA fragments only.
What is an 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.
What is the purpose of DNA ladder?
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 does 1 kb ladder mean?
The 1 kb DNA ladder is a unique combination of a number of plasmids digested with restriction enzymes and PCR products to yield 13 DNA fragments that are suitable for use as a molecular weight standard for electrophoresis.
What is the purpose of the DNA ladder in gel electrophoresis?
How many DNA fragments are in 50 bp DNA ladder?
Invitrogen 50 bp DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA in the range of 50 bp to 2,500 bp. 50 bp DNA Ladder consists of 17 individual chromatography-purified DNA fragments and has reference bands at 2500, 800, and 350 bp for easy orientation.
What does 1 KB plus DNA ladder do?
Description Invitrogen 1 Kb Plus DNA Ladder is designed for sizing and approximate quantification of double-stranded DNA in the range of 100 bp to 15,000 bp. 1 Kb Plus DNA Ladder consists of 18 individual chromatography-purified DNA fragments and has a reference band at 1,500 bp for easy orientation.
Is the Invitrogen DNA ladder composed of double stranded DNA?
Invitrogen DNA ladders are composed of double-stranded DNA fragments only. Are there any suggestions to improve the detection of the bands of my DNA molecular weight ladder in an agarose gel?
How much DNA ladder is in a gel?
