A method for the determination of a partner in an immunochemical reaction, in which one of the partners, which is dissolved in an aqueous fluid, is allowed to react with the other partner, which is covalently bonded to a solid phase, which comprises allowing the reaction to take place in the presence of 0.1 to 3 g/100 g of the aqueous fluid of a surfactant of the formula I CH3-(CH2)m-R-(CH2-CH2-O)n-HI in which R is O, NH or CH=CH-(CH2)p-O with m being 3-26, n being 7-40 and p being 5-15, and an agent suitable for this purpose, are described. |
