но тогда это уже не протаргол будет вероятно.
И сами же в статье и рассказали почему они считают свой staining agent протарголом хотя наверно правильнее было бы назвать его протарголсодержащим.
Цитата:
IN 1897, chemist Arthur Eichengrun submitted a U.S. patent application for “silver albumose” on behalf of the German chemical company, IG Farben. The compound, marketed under the trademark “Protargol”, was introduced as a more effective and less irritating alternative to the noxious silver nitrate solutions then in use for the treatment of gonococcal infections. Today, the compound is almost exclusively referred to in the generic (i.e.protargol).
