Barban PS, Misenzhnikov AV: [Design of stable immunoglobulin erythrocyte diagnostica. 1. Zh Mikrobiol Epidemiol Immunobiol. 1979 Apr;(4):50-6.
Erythocyte fixation and their sensitization by specific immunoglobulins]. The work presents the results of developing the method of fixation of erythrocyte constituting the cellular base of immunoglobulin erythrocytic diagnostic preparations and the sensitization of erythrocytes with immunoglobulin preparations of various specificity. Based on Ingraham's method, modified method of erythrocyte stabilization has been developed; it consists in the treatment of 50% cell suspension with 4% formaldehyde solution in the presence of 0.5% sucrose (erythrocyte suspension and formaldehyde solution being in the ratio 1 : 2.5). An economic and highly productive technique of sensitizing erythrocytes with immunoglobulin preparations has been developed. The essence of this technique lies in the interaction between 6% suspension of erythrocytes treated with formalin and tannin and the equal volume of sensitin taken in a working dose. The work also presents the method of synthesizing the bifunctional compound fluoro-borate bis-daizonium complex (obtained from benzidine) and discusses the comparative possibilities of the methods of developing immunoglobulin erythrocytic diagnostic preparations by sensitization of tannin-treated erythrocytes and by chemical conjugation. |
