...G. Csaba; P. Kovács Proline-glycine, proline-leucine and proline-valine dipeptides and their retro variants were used in the experiments to study the effects of pretreatment (imprinting) in Tetrahymena, by investigating fluorescein isothiocyanate (FITC)-conjugated peptide binding. The protozoan...

...G. Csaba; L. Kôhidai L-alanine and its peptides (L-Ala-2–6) do not attract or repulse Tetrahymena in a 10 −8 M concentration. In 10 −10 M concentration there is a consistent repellent effect. Twenty four hours after L-alanine or L-alanine-peptides' pretreatment (imprinting) the progeny generation...

...G. Csaba; Zsuzsa Darvas Certain non-hormone oligopeptides have a greater imprinting effect on Tetrahymena than others. The imprinting potential is unrelated to the length of the peptide chain, but seems greatly dependent on the amino acid sequence. The direct growth-stimulant action developed...
