Abstract

Abstract Device for the carrying out of an immunochemical determination comprising at least one holder which is provided with an opening at the top and to the inside of which an immunochemically active substance has been applied and which is closed at the top by a removable closure means, the holder containing at least a second immunochemically active substance which, in the absence of test medium, in the form in which the said second immunochemically active substance is contained in the closed holder, during storage and transport under normal conditions exhibits no interaction with the inside of the holder and is inert with respect to the immunochemically active substance applied thereto, characterised in that the holder contains a solid, more or less spherical, freeze-dried particle which contains the second immunochemically active substance.
