The invention relates to steps for the development or the quality control of recombinant monoclonal antibodies (MoAbr) used as medicaments, and also to the selection of the patients liable to effectively respond to a treatment with a given monoclonal antibody. More specifically, the invention relates to a method for evaluating, in vitro, the effector functions of NK cells in response to a test monoclonal antibody, comprising at least the following steps: (i) the NK cells are brought into contact with said monoclonal antibody, which is fixed on a support, in the presence of an agent for inhibiting the secretion of cytokines by said cells; (ii) by way of positive control for the activation of the NK cells, the same experiment is carried out using, in place of the test monoclonal antibody, a monoclonal antibody directed against the Fc RIIIa receptor; (iii) after an incubation period of at least 1 hour, the response of the NK cells is observed by measuring the presence of the CD107 marker at the cell surface, and also the presence of intracellular IFN and/or of intracellular TNF.
