    摘要: A homogeneous, non-competitive, double receptor agglutination assay for measuring immunosuppressant drugs is described. The assay employs at least two receptors wherein each receptor is specific for a separate binding site on the drug and wherein each receptor is bound to a detection particle. The immunosuppressant drug binds to the receptors and causes particle agglutination, which can be measured and correlated with the presence or amount of immunosuppressant drug in a sample.

    摘要: The invention relates to a modified IMPDH polypeptide wherein the IMPDH polypeptide has a histidine tag and where the subdomain of the IMPDH polypeptide is modified so that the rate stability of the histidine-tagged, modified IMPDH polypeptide is maintained relative to the wild-type IMPDH polypeptide. The invention also relates to a method, nucleic acid molecules, vectors, and host cells for producing such a histidine-tagged, modified IMPDH polypeptide, and to kits comprising the histidine-tagged, modified IMPDH polypeptide.

    摘要: Cell separation compositions and associated methods effective for separating cells from various biological specimens such as blood are disclosed. The biological specimens are contacted with the cell separation compositions and centrifuged. The cells are separated based upon their buoyant density in the cell separation composition. The cell separation composition contains colloidal silica particles covalently linked to an organosilane having a non-ionic, hydrophilic group.
