| Sanger Coulson method | The most popular method of DNA sequence determination (c.f. Maxam Gilbert sequencing). Starting with single stranded template DNA, a short complementary primer is annealed and extended by a DNA polymerase. The reaction is split into 4 tubes (called A, C, G or T) each containing a low concentration of the indicated dideoxy nucleotide, in addition to the normal deoxynucleotides. Dideoxynucleotides, once incorporated, block further chain extension and so each tube accumulates a mixture of chains of lengths determined by the template sequence. The 4 reactions are denatured and run out on an acrylamide sequencing gel in neighbouring lanes and the sequence read up the gel according to the order of the bands. (18 Nov 1997) |

| Sanger's reagent | A reagent used to combine with the free NH2 group of the NH2-terminal amino acid residue in a peptide, thus marking this residue; the combined forms are known as DNP-proteins, Dnp-aminoacyl, etc., the fluorine having been replaced to leave a dinitrophenyl residue (DNP, Dnp, or N2Ph-) attached to the NH2 group. Synonym: Sanger's reagent. Acronym: FDNB (05 Mar 2000) |

English biochemist who determined the sequence of amino acids in insulin and who invented a technique to determine the genetic sequence of an organism (born in 1918) United States nurse who campaigned for birth control and planned parenthood; she challenged Gregory Pincus to develop a birth control pill (1883-1966)

| Sanger |
(1883-1966) US nurse in New York slums, where she was appalled at deaths of poor women from self-induced abortions. She coined the term birth control and founded National Birth Control League in 1914. When she opened a birth-control clinic in Brooklyn in 1916, she was arrested for creating a public nuisance. Her struggle with the law dramatized her cause and won doctors the right to dispense birth-control information to their patients. ...
