1. A method for determination of the antigen content of a sample by the antigen-antibody reaction, comprising diluting at least one of the two reaction components with a physiological saline solution, which contains polyethyleneglycol and a buffer substance, thereafter combining both reaction components and determining the antigen-antibody-reaction photometrically, characterized in that the buffer substance is a glycine, glycyl-glycine, acetate, citrate, N,N-bis-(2-hydroxyethyl)-glycine, histidine/HCl, 2-amino-2-(hydroxymethyl)- 1,3-propanol or 5,5-dialkyl-barbituric acid buffer. |
