摘要

A method of qualitatively or quantitatively determining a component of a complex formed between at least one specific binding agent and its corresponding bindable substance. Said method comprises labelling at least one component of said complex with a marker which is easier to determine than the complex itself, whereby the marker used consists of latex particles which can be detected visually either by colour or fluorescence. Preferably the marker consists of coloured or colourable latex particles and the determination is based on the colour characteristics of the latex particles as such or, in the instance that colourable latex particles are used, on the colour characteristics of the coloured particles derived therefrom. The colour, respectively fluorescence signal is, if necessary after development, easily detected and optionally quantified. The invention further comprises coloured or colourable latex particles coated with specific binding proteins and test kits containing the same.
