Abstract RU 2781640 C2

FIELD: medicine.

SUBSTANCE: present invention relates to the field of medicine, namely to a method for in vitro targeted impact on extracellular vesicles with phosphatidylserine exposed on the surface. The specified method includes a stage of introduction of a molecule containing a gamma-carboxyglutamic acid component (hereinafter – GLA-component), wherein the specified GLA-component contains GLA-domain or its active fragment and does not contain an active catalytic domain of GLA-protein, into liquid, which may contain an extracellular vesicle. In this case, the specified GLA-domain or its active fragment are independently selected from thrombin, factor VII, factor IX, factor X, protein C, protein S, protein Z, osteocalcin, GLA-matrix protein, GAS6, transthyretin, periostin, GLA 1 enriched in proline, GLA 2 enriched in proline, GLA 3 enriched in proline, and GLA 4 enriched in proline.

EFFECT: present invention provides the use of molecules for detection of extracellular vesicles expressing phosphatidylserine, isolation of extracellular vesicles, targeted impact on extracellular vesicles, and/or loading of vesicles, for example, with therapeutic materials.
