  • Patent number: 8211367
    Abstract: A method of separating a cell-containing sample into a substantially cell-depleted portion, and a cell-containing portion comprising at least one of a stem cell, a lymphocyte, and a leukocyte comprises a step in which the sample is received in a vessel with at least one flexible wall. In another step, an additive and particles are added to the sample, wherein the additive substantially binds to the at least one of the stem cell, lymphocyte, and leukocyte, and the particles and wherein the particles substantially bind to the at least one of the stem cell, lymphocyte, and leukocyte, and the additive, thereby producing a cell-containing network. In a further step, the network is separated from the substantially cell-depleted portion by applying a magnetic force.

  • Publication number: 20080311568
    Abstract: Contemplated methods and kits include a plurality of single stranded oligonucleotides that comprise a discriminating sequence that is encompassed on one end by a label and on the other end by a unique tag sequence. In one preferred aspect, the discriminating sequence is an RNA repeat unit, forms a heteroduplex with a complementary DNA repeat unit of the target nucleic acid, and the discriminating agent is RNaseH. Using such systems, the number of repeat units can be simply identified by hydrolysis of the discriminating sequence where such sequence is adjacent to a predetermined number of DNA repeat units in the single stranded oligonucleotide.

  • Patent number: 6291249
    Abstract: A cell containing sample is separated into a cell containing portion and a substantially cell depleted portion, by mixing the sample with particles to produce a cell containing network, and separating the network from the remaining substantially cell depleted portion within a plurality of confining walls, wherein at least one of the walls is flexible. While in some aspects the separation is performed employing a magnetic force, in other aspects the separation is performed using two forces, wherein one force is a magnetic force and the other force is a mechanical force. It is contemplated that whole blood may be used as the sample, and that the cell-containing portion largely comprises a network of inter-linked red blood cells. It is especially contemplated that separation involves antiligands, preferably primary antibodies that bind to a ligand such as antigen on or in red blood cell membranes, and secondary antibodies that bind to the primary antibodies.
