A method and compositions are provided to effect optimization of methods for determining concentrations of antibodies or antigens. Particles coated with an antigen or an antibody are suspended in an aqueous medium where pH and ionic strength are controlled so that the coulomb effect and the van der Waals forces on and exerted by the particles are balanced.
