Abstract: A method for obtaining blood plasma from a whole blood sample comprising the following steps a) contacting the whole blood sample with a composition (A) comprising at least one carboxylic acid, wherein the addition of the acidic composition (A) and optionally further additives to the whole blood sample provides a sample mixture having a pH that lies in a range from 2.5 to 5; b) binding red and white blood cells to a magnetic solid phase; wherein step a) and step b) can be performed sequentially or simultaneously, c) separating the solid phase with the bound cells from the remaining sample thereby providing blood plasma.

Abstract: The present invention pertains inter alia to a method for analyzing a sample comprising biomolecules, which comprises the following steps: A a) lysing the sample to provide a lysed sample and optionally clearing the lysed sample; b) contacting at least a portion of the lysed sample with a dry composition comprising reagents for performing the analytical method, thereby providing a reconstituted composition; c) performing an analytical method using the reconstituted composition; or B a) contacting the sample with a lysis solution thereby providing a lysis mixture; b) using the lysis mixture to reconstitute a dry composition comprising reagents for performing the analytical method, thereby providing a reconstituted composition; c) performing an analytical method using the reconstituted composition, wherein the reconstituted composition is optionally cleared and wherein subsequent to step b) at least one step is performed which supports the lysis of the sample.

Abstract: A method for determining whether a lysate contains sufficient biological sample material for a nucleic acid amplification reaction that includes preparing the lysate in the presence of at least one compound that inhibits the amplification reaction if insufficient biological sample material was present during preparation of the lysate, but does not inhibit the amplification reaction if sufficient biological sample material was present during preparation of the lysate, subjecting the lysate to the amplification reaction, and analyzing a result of the amplification reaction. Due to the presence of the compound in the amplification reaction, no amplification signal is obtained if insufficient biological sample material was present during preparation of the lysate but an amplification signal is obtained if sufficient biological sample material was present during preparation of the lysate.
