| 20110198293 | MAGNETIC SEPARATING DEVICE - The disclosure relates to a magnetic separating device for isolating magnetically labelled particles from a non-magnetic medium comprising a body portion ( | 08-18-2011 |
| 20100301257 | MONODISPERSE SUBMICRON POLYMER PARTICLES - This invention relates to monodisperse cross-linked polymer particles, comprising particles with a substantially smooth outer surface and an average diameter of less than 1 μm, wherein the particles are solid or porous, and wherein the coefficient of variation (CV) % of the particles, when measured by CPS disk centrifugation analysis, is less than 15%. These monodisperse cross-linked polymer particles may comprise magnetic material and are useful in various application. This invention also relates to monodisperse polymer particles for use as seed particles in the Ugelstad process. | 12-02-2010 |
| 20100207051 | PARTICLES AND THEIR USE IN A METHOD FOR ISOLATING NUCLEIC ACID OR A METHOD FOR ISOLATING PHOSPHOPROTEINS - Monodisperse polymer microparticles comprising polystyrene or polyacrylate, wherein said particles have a coating formed of at least one transition metal oxide or porous polymer microparticles comprising polystyrene or polyacrylate, wherein said particles have a coating formed of at least one transition metal oxide. The use of such particles in a method for isolation of phosphoproteins from a sample containing phosphoproteins or for isolating nucleic acid from a sample containing nucleic acid is also described | 08-19-2010 |
| 20100068193 | METHODS AND MATERIALS FOR THE GENERATION OF REGULATORY T CELLS - Methods are disclosed for the generation of immunosuppressive regulatory T cells. The methods can include contacting a population of CD4+CD25− T cells with a T cell receptor (TCR)/CD3 activator, a TCR co-stimulator activator, and rapamycin. Kits for the generation of immunosuppressive regulatory T cells, methods of use, and cell populations are also disclosed. | 03-18-2010 |
| 20100006509 | MAGNETIC SEPARATION APPARATUS - A magnetic separation device ( | 01-14-2010 |
| 20080293035 | Nucleic Acid Isolation - The present invention relates to a method of isolating nucleic acid from a blood sample, said method comprising: (a) selectively isolating leucocytes from said sample by binding said leucocytes to a solid support by means of a binding partner specific for leucocytes; (b) lysing said isolated leucocytes; and (c) binding nucleic acid released from said lysed cells to said solid support. Kits for isolating nucleic acid from samples form further embodiments of the invention. | 11-27-2008 |
| 20080255004 | METHODS OF REVERSIBLY BINDING A BIOTIN COMPOUND TO A SUPPORT - Methods of reversal of the binding between a biotin compound and a biotin-binding compound are disclosed. A method of reversibly releasing a biotinylated moiety from a streptavidin (or avidin) coated support is shown as an example. The strong interaction between streptavidin or avidin-biotin is made much weaker by using a combination of modified streptavidin or avidin and modified biotin like desthiobiotin or a derivative thereof like DSB-X Biotin. A protein, such as an antibody may be biotinylated with the modified biotin. When this protein is isolated by binding the modified biotin to the modified streptavidin or avidin bound to an solid surface, it may be released under very gently and very rapid conditions by addition of free biotin. In contrast to proteins obtained by the prior art release methods the protein obtained using the previously available release methods, the proteins obtained using the methods disclosed herein will maintain their native conformation. Uses of the methods in various procedures including cell detachment procedures and techniques of detection, identification, determination, purification, separation and/or isolation of target proteins or nucleic acid molecules are also described. | 10-16-2008 |
