Abstract: Methods for preparing Factor X, activated Factor X, inactivated factor X and inactivated factor Xa, compositions comprising Factor X and Factor Xa, inactivated Factor X and inactivated Factor Xa and methods of medical treatment using Factor X, Factor Xa, activated Factor X and inactivated Factor Xa are disclosed. The preparation methods comprise a chromatography step using an immobilised metal ion affinity chromatography substrate.

Abstract: The invention provides a method for determining the angiogenic signature of a cell or tissue sample and methods for predicting efficacy of angiogenic therapy, for preparing a predictive model for predicting angiogenic potential, for identifying an agent for use in angiotherapy and therapeutic agents and applications.

Abstract: Haptoglobin (Hp) removes cell-free Hemoglobin (Hb), with different physiological effects depending on the particular Hp polymer. We propose that material enriched for alpha 1 chain Hp polymeric forms, such as those made from Cohn fraction V precipitate, will be more suitable for the treatment of certain diseases benefiting from both an antioxidant and anti-inflammatory component, such as for hemolytic disease. Material enriched for alpha-2 chain Hp polymeric forms, made for example from Cohn fraction IV precipitate, will be more suitable for treatment of diseases where an angiogenic, and/or inflammatory affect, and/or limited extravasation is desirable.

Abstract: The present invention relates to processes for the purification of fibrinogen, and to readily solubilised fibrinogen preparations.

Abstract: The invention relates to methods for the isolation of AAT from solutions containing albumin and AAT using at least two separate metal chelate chromatography steps. The product may be further purified and/or subjected to one or more virus inactivation or reduction steps. The isolated AAT may then be formulated for pharmaceutical use.

Abstract: The invention provides a method for the isolation of haptoglobin from a sample comprising Cohn fraction V, wherein said method comprises anion exchange chromatography of said sample. The product may be further purified and/or subjected to one or more virus inactivation or reduction steps. The isolated haptoglobin may then be formulated for pharmaceutical use.
