Abstract: Device for collection of liquid samples has a pump (16) for pumping sampling liquid (24), a tube (7) for delivering the sampling liquid, sample container (23) for collection of the sampling liquid, and a transport device for moving the tube in succession from one sample container to the next sample container in at least one row of sample containers. An elastic cloth (22) is sealingly applied over the openings of the sample containers, and a slit (21), in which the tube (7) runs, is arranged in the cloth. The transport device is arranged to stop the tube when it is in a position over the sample container.

Abstract: A method is disclosed for the recovery of a peptide-containing compound from a solution by the use of a ligand attached to a carrier which ligand is capable by biospecific affinity of fixing onto the peptide-containing compound. The carrier which, for example, may be a soluble macromolecule, e.g., cellulose or dextran, with ligand attached thereto, is utilized in dissolved form. The choice of ligand is determined by the type of peptide-containing compound for which it is to be used. Example of ligands which may be used are immunoglobulins, Fc-receptors, certain surface receptors from bacteria, e.g., protein A from S. aureus, co-factors and certain sugar-containing proteins. The ligand may be attached to the carrier by bonds of a covalent character, which may be achieved by periodate activation and subsequent coupling or by diimidazole coupling.
