Alkylhydroxybenzenes (AHBs) are a large group ofbiologically active substances of microbial and plantorigin that are capable of nonspecific interaction withdifferent biopolymers [1–7]. AHB homologues differin the length of the alkyl radical, which determines thedegree of hydrophobicity of the molecules and theirreactivity [1, 2]. The functioning of AHBs as “chemical chaperones” [3, 4] determines the development ofeffects in different systems. For example, changes inthe presence of micromolar concentrations of AHBswere shown for the catalytic activity of some enzymes[3, 4], the physicochemical properties of DNA [5],and the antigenbinding ability and functional activityof antibodies [6, 7]. It was also shown that the molecular weight and sizes of proteins modified with AHBsaltered [3]. However, information about the effect ofAHB on the dimensional characteristics of immune complexes is missing.
