DNA and Protein Markers

DNA and protein markers, also known as molecular weight ladders, are essential standards used in gel electrophoresis to determine the size of DNA fragments or proteins. These ready-to-use ladders provide sharp, consistent bands across a wide range, enabling accurate size estimation, verification of amplification products, and monitoring of protein expression or purification. They are widely applied in molecular biology, cloning, sequencing, and protein research to ensure reliability and reproducibility of experimental results.
