The conditions of the activation of immunological memory by means of flagellin and its conjugate with polyacrylic acid (PAA) have been studied. The flagellin-PAA conjugate has proved to be capable of inducing the appearance of memory cells when introduced in doses, considerably lower (0.01 and 0.001 micrograms) than those of native protein (0.1, 1 and 10 micrograms). At the same time no manifest differences in the reactivation of flagellin-induced and conjugate-induced memory cells by the antigen have been established. Immunization with protein, as well as with its conjugate, has been found to induce the formation of mainly anti-Hi : 1,2 IgG in secondary immune response.
