    摘要: A method includes creating a mixture in a container, the mixture including a sample containing at least one molecule of nucleic acid, at least one magnetically-responsive particle, and a remainder; and providing the mixture with a pH of less than about 7.0, thereby altering the surface charge properties of the at least one magnetically-responsive particle. The alteration in the surface change properties of the at least one magnetically-responsive particle causes the at least one molecule of nucleic acid to become non-specifically bound to the at least one magnetically-responsive particle to form a complex. Preferably, the at least one magnetically-responsive particle is uncoated, untreated, lacks surface modification, and has a diameter of about 0.1 μm to about 1.0 μm.

    摘要: A method useful for the reversible binding of a protein molecule in a biological sample. The method uses paramagnetic particles having an associated electronic charge to bind proteins with the opposite charge to form a particle/protein complex. The complex can be immobilized to a container wall by applying a magnetic field to the particle/protein complex. The sample may be further processed to obtain a protein sample in a more pure form or a sample depleted of select proteins.

    摘要: A filled pastry having a cooked dough shell and a filling. The cooked dough shell is made from raw dough that includes whole-wheat flour, wheat bran, sweetener, shortening, and water and can have an appearance and flavor that is similar to graham crackers. The filling is prepared from a material that is distinct from the dough shell. The filling is substantially retained within the dough shell. An interface between the dough shell and the filling minimizes moisture migration.
