FIELD: biotechnology.SUBSTANCE: method of binding Mycobacteria and/or fragments of Mycobacteria is provided, which present in an aqueous liquid with the solid surface. The said liquid is added to a sufficient amount of a water soluble polymer in the presence of a solid surface to displace Mycobacteria and/or their fragments from the said liquid onto the solid surface. The surface may be provided in the form of a microsphere. The water-soluble polymer can be selected as, for example, dextran, polyethylene glycol, polyvinylpyrrolidone.EFFECT: invention enables to implement binding to a solid surface of Mycobacteria and their fragments that are not precipitated under conditions of centrifugation.19 cl, 11 ex |
