摘要:
A fission product of an immunoglobulin having an immunologically functioning Fc-portion is bound to a carrier by adhesion or a chemical reaction. It can be used in an immunological analytic process for the determination of Fc-reactants in aqueous solutions.
摘要:
What is disclosed is a method for the therapy of immunocomplex diseases with an agent which contains Fc-reagents that react with the Fc-part of the antibody contained in the immunocomplex, but which themselves do not posses an immunologically active Fc-part or an Fc-part capable of being activated.
