[Fc mu R on neutrophils].

To detect Fc mu R, use was made of human and animal neutrophils. The detection of the receptors was possible only after the use of special manipulations: 1) cultivation for 18 h in a IgM-free of IgM-low medium, 2) treatment of neutrophils with hypotonic shock and then with acetate buffer solution. Both the methods provided similar results, permitting the detection on an average of 13-22% of neutrophils (up to 39%) carrying the receptors under consideration.
