FIELD: biotechnology.
SUBSTANCE: monocytes are isolated from venous blood MNCs using the Percoll cushion bi-gradient of density: 47.5% SIP and 15% SIP, respectively, at cooling to +4°C. The monocytes are placed in a completely nutritional culture medium with adding 20 ng/ml IL-4 and 20 ng/ml GM-CSF. The completely nutritional culture medium is replaced on the day 3 of cultivation. On the day 4 of cultivation the antigen of infectious origin Opisthorchis felineus is added at a dose of 40 mcg/ml and maturation of dendritic cells is simultaneously induced with lipopolysaccharide E.coli of serotype 055: B5 in a dose of 1 mcg/ml. On the day 6 of cultivation the dendritic cells are washed and analysed.
EFFECT: use of the method provides obtaining the mature, antigen-loaded dendritic cells.
