[Latex immunoassay]

The latex immunoassay can be considered a quickly practicable and simple methodic variant of the immunoassay. In this work principles and present capability of this assay are stated. Own experiments deal with the adsorption reaction of alkaline phosphatase and horseradish peroxidase at polystyrol respectively melanin formaldehyde lattices. The adsorption reaction of several lattices is partly extremely different. Problems concerning the construction of an assay useful for practical purposes are discussed.
