1907 Jrnl. Med. Res. 17 232 The complement, when incubated with antigen and low (1/ 10) dilution of immune serum, may..be absorbed through the union of precipitin and precipitinogen.
1953 R. W. Fairbrother Text-bk. Bacteriol. (ed. 7) xv. 196 Methods used for this purpose..are..(1) the precipitin tests of Lancefield, using the ‘C’ precipitinogen, to determine whether the strain isolated belongs to group A. (2) The agglutination method of Griffith, by which group A strains are typed.
