Abstract: The present invention relates to a method of ensuring the effectiveness of the extraction workup from a biological sample of nucleic acid. The inventive method is able to distinguish between possible defects in the extraction of nucleic acid from a sample and possible defects in a subsequent amplification step. The present invention also relates to a packaged array for extracting nucleic acid from a biological sample.

Abstract: The present invention relates to methods for pretreating biological samples for extraction of nucleic acid therefrom. The present invention employs a combination of at least one protein denaturant with one or more of the following elements to form a reaction mixture for extraction of nucleic acid: (1) at least one aprotic solvent, (2) stepwise heating, and (3) sample dilution.

Abstract: A composition and method for the purification of nucleic acid are disclosed. The composition includes at least one alkaline agent and at least one detergent. The composition preferably also includes a suspension of paramagnetic particles and an acidic solution. The method involves the use of the composition with paramagnetic particles to extract nucleic acid from a biological sample.

Abstract: Methods for isolating a compound from a multipart, typically biological sample. The methods use at least one paramagnetic particle having an associated electronic charge to bind compounds with the opposite charge to form a particle/compound complex. Alternatively, the paramagnetic particles have a ligand or functional group with an affinity for a target compound to form a particle/compound complex. The complex can be immobilized 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 compounds.

Abstract: 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.

Abstract: 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.

Abstract: 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 ?m to about 1.0 ?m.
