What are the applications of 1 kb DNA ladders?

The most notable application of the 1 kb DNA ladder is for determining the size of double-stranded DNA fragments with lengths ranging from 250 bps to 10,000 bps.

Establishing the sizes of DNA fragments facilitates the quantification of DNA fragments and provides insights into their relative sizes compared to each other.

These DNA size standards serve as valuable controls throughout the electrophoresis procedure.
