Two inactive M13 sequencing kits for DNA sequencing by Amersham International plc, 1987
M13 is a bacteriophage – a virus that infects certain types of bacteria – which contains a single strand of DNA. Sold for laboratory use only, this now inactive M13 kit was used for DNA or gene sequencing. This technique is used by scientists studying DNA to determine the order of base pairs (adenine, thymine, guanine, cytosine). These pairings establish which amino acids are produced in the body. The kit was made by Amersham International plc.
