Maxam–Gilbert sequencing is a method of DNA sequencing developed by Allan Maxam and Walter Gilbert in 1976–1977. This method is based on nucleobase-specific partial chemical modification of DNA and subsequent cleavage of the DNA backbone at sites adjacent to the modified nucleotides. [1] An example Maxam–Gilbert sequencing reaction.
Walter Gilbert and Allan Maxam developed a DNA sequencing method - now called Maxam-Gilbert sequencing - which combined chemicals that cut DNA only at specific bases with radioactive labeling and polyacrylamide gel electrophoresis to determine the sequence of long DNA segments. [3] Allan Maxam and Walter Gilbert’s 1977 paper “A new method ...
The first DNA sequencing methods were developed by Gilbert (1973) [8] and Sanger (1975). [9] Gilbert introduced a sequencing method based on chemical modification of DNA followed by cleavage at specific bases whereas Sanger's technique is based on dideoxynucleotide chain termination. The Sanger method became popular due to its increased ...
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...
The DNA template with the protein will result in ladder distribution with a break in it, the "footprint", where the DNA has been protected from the cleavage agent. Note: Maxam-Gilbert chemical DNA sequencing can be run alongside the samples on the polyacrylamide gel to allow the prediction of the exact location of ligand binding site.
Allan Maxam and Walter Gilbert's 1977 paper "A new method for sequencing DNA" was honored by a Citation for Chemical Breakthrough Award from the Division of History of Chemistry of the American Chemical Society for 2017. It was presented to the Department of Molecular & Cellular Biology, Harvard University. [36] [24]
See the "chain termination method" page for an example of a polyacrylamide DNA sequencing gel. Characterization through ligand interaction of nucleic acids or fragments may be performed by mobility shift affinity electrophoresis. Electrophoresis of RNA samples can be used to check for genomic DNA contamination and also for RNA degradation.
The method uses an enzyme, deoxyribonuclease (DNase, for short), to cut the radioactively end-labeled DNA, followed by gel electrophoresis to detect the resulting cleavage pattern. For example, the DNA fragment of interest may be PCR amplified using a 32 P 5' labeled primer, with the result being many DNA molecules with a radioactive label on ...
