FIELD: medicine.
SUBSTANCE: invention can be used for evaluating the antibody level in blood serum by enzyme-linked immunosorbent assay (ELISA) in diagnostics of the diseases caused by capsular forms of such agents, as Meningococcus, Pneumococcus, Streptococcus, Haemophilus, Neisseria, Salmonella, Klebsiella, Pseudomonas, and also for evaluating the postvaccinal immunity level.
EFFECT: covalent binding of polysaccharide to the protein pre-immobilised on the tray surface ensures reliable and simple antigen fixation that does not involve effect of foreign chemical groups on the analysis results that leads to simplification of the method for tray sensitisation in the ELISA reliability control.
