Abstract: In order to quantitatively characterize biological objects, for example individual cells, a stimulus is applied to a biological object (8) in a contactless fashion. A measurement and a further measurement are performed on the biological object (8) in order to ascertain a response of the biological object (8) to the stimulus, wherein the measurement and the further measurement comprise detecting Raman scattering on and/or in the biological object (8) and/or capturing data using digital holographic microinterferometry (DHMI). The biological object (8) is characterized according to a result of the measurement and is sorted if needed. The stimulus can be applied by means of a laser beam that creates optical tweezers or an optical trap, by means of ultrasonic waves or an electric or magnetic radio frequency field.

Abstract: The present invention includes methods for preparing anticoagulant polysaccharides using several non-naturally occurring, engineered sulfotransferase enzymes that are designed to react with aryl sulfate compounds instead of the natural substrate, PAPS, to facilitate sulfo group transfer to polysaccharide sulfo group acceptors. Suitable aryl sulfate compounds include, but are not limited to, p-nitrophenyl sulfate or 4-nitrocatechol sulfate. Anticoagulant polysaccharides produced by methods of the present invention comprise N-, 3-O-, 6-O-sulfated glucosamine residues and 2-O sulfated hexuronic acid residues, have comparable anticoagulant activity compared to commercially-available anticoagulant polysaccharides, and can be utilized to form truncated anticoagulant polysaccharides having a reduced molecular weight.
