| 20100133181 | SYSTEMS AND METHODS FOR PROCESSING COMPLEX BIOLOGICAL MATERIALS - Method and systems, for processing biological material, that contain a biological material in a vessel; add an aggregating agent to the material in the vessel and allow the material to separate into two or more distinct submaterials; extract one or more of the submaterials from the vessel; automatically transport one or more of the submaterials remaining in the vessel to a filtration device; and collect a resulting target retentate into a target retentate receptacle. | 06-03-2010 |
| 20100151438 | METHODS AND KITS FOR ENHANCING SEDIMENTATION AND RECOVERY OF CELLS IN A SAMPLE - The methods and kits provide sedimentation-enhancing agents that significantly increase the efficiency of cell-sedimentation. They also increase the efficiency of blood cell separation methods and thereby increase the recovery of total nucleated cells. | 06-17-2010 |
| 20100155325 | PARTICLE-TEMPLATED MEMBRANES, AND RELATED PROCESSES FOR THEIR PREPARATION - A method for the formation of a membrane is described. A collection of substantially spherical particles formed from a selected material is contacted with at least one reactive material. The reactive material is cured or otherwise polymerized by various techniques, so that it forms a matrix that substantially surrounds and contains the particles. A portion of the particle material is then removed, so that the matrix contains a pattern of pores that are permeable to selected substances in solution. In some instances, the matrix is formed by an interfacial reaction between at least two reactive materials. Related filtration membranes are also described. | 06-24-2010 |
| 20110240550 | BLOCK COPOLYMER MEMBRANES AND ASSOCIATED METHODS FOR MAKING THE SAME - A separation matrix comprises a porous surface layer; and a bulk porous support, wherein both the porous surface layer and the bulk porous support comprising a block copolymer. The block copolymer comprises A-B or A-B-A repeating units, wherein A and B at each occurrence are two different blocks of oligomer, or polymer. A structural unit of block A is derived from one or more atom transfer radical polymerization (ATRP)-active monomer or oligomer and a structural unit of block B is derived from a thermoplastic ATRP-active macro initiator. A poly dispersity index of the block copolymer is at least about 2. | 10-06-2011 |
