Abstract
The invention relates to a rigid mask intended for the deposition, spreading and incubation of one or several liquids on a gel (of total surface Sg) according to one or several well-defined zones of the gel, hereafter designated by "incubation surface Si", this mask comprising: an upper surface which is in particular flat and a lower surface which is in particular flat, in particular substantially parallel to each other, at least one orifice intended to permit deposition and spreading of the liquid on the incubation surface Si of the gel, and at least one slit crossing the mask over the whole of its thickness and intended to permit withdrawal of the excess of liquid present on the incubation surface Si of the gel, PA0 the lower surface of the mask being intended to be deposited in proximity to the surface Sg of the gel, under conditions such that the lower surface of the mask is not in contact with the incubation surface Si. Application to the development of a gel previously subjected to the electrophoresis of proteins.
