Reaction Kit for DNA research, United States, 1999
This kit was developed for analysing Deoxyribonucleic Acid (DNA). This is the chemical that carries the genetic information in the cell. Researchers use the reaction components within the kit to read the information encoded within the DNA. The DNA is prepared for analysis on a special silicon chip (known as a SpectroCHIP). A mass spectrometer is then used to identify differences in the DNA by measuring changes in the mass or weight of the molecule. This technique was developed in the 1990s by Sequenom, in San Diego, California.

DNA stores the information, or blueprints, of every cell and is located in the genes. It is made up of two strands which form a double helix that is linked by hydrogen bonds. It was first described in 1953 by Francis Crick and James Watson.
