Maxam-Gilbert method

DNA sequencing

Quick Summary

The Maxam-Gilbert method is one of the foundational techniques for DNA sequencing, a process that determines the order of nucleotides (A, C, G, and T) within a DNA molecule. Developed by Allan M. Maxam and Walter Gilbert in the 1970s, this method relies on the differential chemical reactivity of the DNA bases. Through a series of chemical reactions, specific bases are selectively cleaved, creating DNA fragments of varying lengths. These fragments are then separated by size using gel electrophoresis, allowing scientists to deduce the original nucleotide sequence. While historically significant, the Maxam-Gilbert method has largely been superseded by more efficient and automated sequencing technologies.123
