Abstract: The present invention provides methods for analyzing a target compound from a biological sample. In one aspect, a method for analyzing a target compound in a biological sample can comprise delivering a biological sample through an affinity column, the affinity column having a binding ligand coupled to a stationary structural support, wherein the affinity column has a high density of the binding ligand per the stationary structural support and wherein the binding ligand has been preselected to cause weak affinity separation zonal retardation of the target compound from the biological sample forming a target compound fraction and a biological sample fraction and detecting the target compound by mass spectrometry.

Abstract: A method of preparing a blood platelet lysate starting from platelet-rich plasma from whole blood of animals, to which blood a citrate has been added to prevent coagulation, is described. The method is characterised by concentrating the platelet-rich plasma by ultrafiltration to obtain a plasma that is richer in platelets, adding water for lysis of the platelets included, adding Ca2+ to the lysed concentrated platelet-rich plasma for forming coagel of other components than lysed platelets, centrifuging the coagel, whereby a clear, bright-red liquid of blood platelet lysate is obtained, which substantially consists of lysed platelets, and a coagulate, and, after centrifugation, the liquid going through a filtering step.

Abstract: The present invention relates to a method of screening a biological target for transient weak interactions between the target and a library of ligands. The method includes the provision of a composition comprising a biological target and the provision of a plurality of stationary phases from such a composition. A plurality of ligand compositions is transported to the stationary phases to establish contacts between the ligands and the biological targets. Zonal retardation information are collected for each ligand, downstream of the stationary phases in order to select ligands with dissociation constants (Kd) in the range of 0.01 to 10 mM, exhibiting weak affinity to the target.

Abstract: The invention relates to a high performance affinity chromatographic system characterized by an immobilized active substance interacting weakly (K.sub.diss >10.sup.-3 M) with the desired structure of the type or types of molecule to be separated. The substance is covalently bound in its active state on a carrier of a solid, preferably porous, organic or inorganic material thereby making it suitable for use in the so-called HPLC or HPLAC technique for the separation of e.g. biomolecules. Examples of useful inorganic materials are silica or glass, or organic materials such as plastics or polysaccharides. Separation takes place by the mobile liquid being led through the column packed with the immobilized active substance of weak affinity for the complementary substances. Examples of such immobilized ligands are antibodies or fragments thereof, antigens or fragments thereof and various receptor substances.

Abstract: A chromatographic separation agent composed of a water unsoluble solid substance showing dihydroxyboryl groups.

Abstract: A method for activating immobilized living microorganisms applied to transformations of steroids, antibiotics and other compounds characterized by the addition of peptone, glucose or a mixture of peptone and glucose to the reaction mixture.
