1904 G. H. F. Nuttall Blood Immunity & Blood Relationship ii. 98 The immunifying substance, which they [sc. Obermayer and Pick] wrongly style ‘precipitogen’, as well as the precipitin they conclude are not albuminous. [Note] A misnomer..for the reason that it suggests a relation between precipitin and (‘precipitogen’) precipitable substances such as exists, for instance, between pepsin and pepsinogen, in other words that the ‘precipitogen’ is a forerunner of precipitin, which it is not.
1907 Jrnl. Med. Res. 16 173 Many or all of the other substances are assimilated more or less readily by the tissues, are neutralized in a relatively short space of time, and in some instances (precipitogens) definite reaction products to them may be formed.
