Abstract

The present invention concerns a method for producing microparticles loaded with proteins which is characterized in that the microparticles are loaded in suspension under strongly alkaline conditions. The invention also concerns microparticles which can be produced using this method and their use in a binding test e.g. in an immunoassay.
