RESUMEN
The effect of ionic parameters of the medium (pH and ionic strength) on the processes of interaction of tannin-treated erythrocytes and the protein fractions of human serum (macroglobulins, microglobulins and albumin) was studied in factorial experiments. Complex effect of these parametres on the processes under investigation and optimum conditions of erythrocyte sensitization were established. Subsequent fixation of antibodies by the erythrocyte diagnostic and their agglutinating activity are manifested in different mannera depending on the conditions of preceding sensitization. Important peculiarities were discovered in the mechanism of interaction between the erythrocytes and various serum proteins. The obtained results should be taken into account in the production of erythrocyte antigen and antibody diagnosticums.

The effect of concentration of human serum proteins, duration of contact and temperature of the medium on the process of their interaction with formalized, tannin-treated sheep erythrocytes was studied. Dependence of the process of specific haemosensitization on the enumerated factors was established. The character of the process of haemosensitization by serum proteins and its dependence on the concentration of sensitins and the duration of the contact with them can be expressed by Langmuir's equation. On the basis of limited preliminary experiments it is thus possible to define the optimum conditions for the loading of erythrocytes.
