A 1 kb DNA ladder is a tool used in molecular biology laboratories to estimate the size of DNA fragments in the range of 1,000 base pairs (bp). It is composed of a series of DNA fragments of known sizes, typically ranging from 500 bp to 10,000 bp, that is run on an agarose gel alongside the sample DNA being analyzed. The sample DNA fragments will migrate through the gel based on their size, with smaller fragments moving more quickly than larger fragments. By comparing the migration of the sample fragments to the migration of the known fragments on the 1 kb ladder, researchers can estimate the size of the sample fragments.
1 kb DNA ladders are often used in molecular analysis techniques such as gel electrophoresis and Southern blotting. They can be useful for a variety of applications, including DNA fingerprinting, gene mapping, and the detection of genetic mutations. In these applications, 1 kb DNA ladders help researchers identify and characterize specific DNA sequences, as well as detect and quantify changes in DNA structure or function
The 1kb DNA ladder contains eleven blunt-ended DNA fragments ranging from 500bp to 10kb in increments. The ladder is suitable for sizing PCR products or other double-stranded DNA fragments. The ladder is premixed with loading dye and is ready to use.
