    • A method, apparatus and system for automated removal of an embedding medium from an embedded biological sample. The method comprising the steps of: providing an automated sample processing apparatus having an automated process operation capability that causes automated process operation events through robotic sample process functions; providing a clearing solvent, e.g. an organic solvent, capable of lowering the melting point of an embedding medium and/or dissolving an embedding medium; loading a plurality of carriers with embedded biological samples in the automated sample processing apparatus; exposing an embedded biological sample to the clearing solvent, whereby the embedding medium is liquefied; and providing a washing solution capable of removing the clearing solvent and the liquefied embedded medium from said biological sample, said clearing solvent and said washing solution being immiscible.

    • A method of producing and selectively isolating a desired protein or polypeptide or derivative thereof by constructing a recombinant vector comprising a DNA sequence coding for said desired protein or polypeptide operatively linked to a DNA sequence coding for protein A or an active polypeptide fragment thereof or any other macromolecule capable of binding to the constant regions of immunoglobulins, such that said DNA sequences together code for an IgG-binding fusion product between said desired protein or polypeptide and said protein A, active polypeptide fragment thereof or macromolecule; transforming a compatible host with said recombinant vector such that the combined DNA sequences coding for said fusion protein or polypeptide can be expressed by the host, and culturing the transformed host in a suitable growth medium to produce said fusion protein or polypeptide; selectively isolating said fusion protein or polypeptide by adsorption to an IgG-supporting carrier material; and optionally desorbing said fusion protein or polypeptide from said IgG-supporting carrier, said fusion protein or polypeptide coded for by said combined DNA-sequence optionally comprising a unique cleavage site between said protein A part and said desired protein or polypeptide part, said desired protein or polypeptide part then being cleaved off from the rest of the fusion protein or polpeptide either while the latter is adsorbed to the IgG-supporting carrier or after desorption thereof from the carrier. Also a hybrid vector for use herein, a method and an expression vector for its preparation and a host organism transformed by said hybrid vector are disclosed.
