stabilate Biol.|ˈsteɪbɪleɪt|
[f. L. stabil-is stable a. + -ate, after filtrate, precipitate, etc.]
A sample of biological material from a homogeneous source which is preserved by freezing on a single occasion to serve as a standard, portions of it being restored as desired.
1965Lumsden & Hardy in Nature 6 Mar. 1032/2 A separate term is now required to convey this implication of the stabilization of biological characters in preserved material and to distinguish preserved from ‘strain’ material. The word ‘stabilate’ is now proposed for this purpose. A ‘stabilate’ may be defined as a population of an organism preserved in viable condition on a unique occasion. 1970Ibid. 19 Sept. 1255/1 A stabilate of infected blood was frozen to -70° at the start of each experiment to ensure that a strict homologous challenge of vaccinated animals was subsequently made. 1976Ibid. 24 June 698/2 All eight surviving cattle were challenged with a similar injection of stabilate.
Hence as v. trans., to make into a stabilate.
1978Tropenmedizin und Parasitologie XXIX. 443/2 The isolate was needle-passaged once in a goat and then stabilated. |
