Abstract: The present invention broadly relates to the improved method for purification of capsular polysaccharides. Particularly, the present invention relates to the method of purification of capsular polysaccharides from Streptococcus pneumoniae and other similar related capsular polysaccharides produced from both gram-negative and gram-positive microorganisms. More particularly, the invention involves passing the crude capsular polysaccharide solution through reinforced cellulose membrane having quaternary ammonium, and further contacting the solution with silicon dioxide (SiO2) and isolating the capsular polysaccharide in a pure form. The purified capsular polysaccharide is useful for producing vaccines that contain the polysaccharide alone or are conjugated to proteins.

Abstract: The invention relates to methods for conducting solid-phase binding assays. One example is an assay method having improved analyte specificity where specificity is limited by the presence of non-specific binding interactions.

Abstract: The invention relates to methods for conducting binding assays in an assay device that includes one or more storage and use zone. The storage zones of the assay device are configured to house one or more reagents used in an assay conducted in the use zone of the device.

Abstract: The present invention relates to the process to prepare recombinant lectin having amino acid sequence of SEQ ID NO:1, wherein the process comprises fed-batch fermentation of a clone in a host cell at specific feeding rate with carbon to Nitrogen ratio of 3:1 to 6:1. The invention also relates to the process of purification of recombinant lectin having amino acid sequence of SEQ ID NO: 1.

The invention also relates to assay methods used in connection with the diagnostic methods described herein.

Abstract: The present invention relates to methods and kits to assess an absorbed dose of ionizing radiation and/or the severity of tissue injury from radiation in a patient. The invention also relates to algorithms used to calculate an absorbed dose of radiation based on biomarker measurements of a plurality of biomarkers that are altered relative to a normal control in the event of radiation exposure.

Abstract: Assay cartridges are described that have purification, reaction, and detection zones and other fluidic components which can include sample chambers, waste chambers, conduits, vents, reagent chambers, reconstitution chambers and the like. The assay cartridges are used to conduct multiplexed nucleic acid measurements. Also described are kits including such cartridges, methods of using the same, and a reader configured to analyze an assay conducted using an assay cartridge.

Abstract: A modified lectin protein is provided having at least one amino acid modification in an amino acid sequence of SEQ ID NO. 1 orin an amino acid sequence having at least 60% homology thereto. The amino acid modification is selected from one of more of the following: at least one amino acid modification in a carbohydrate binding site; at least one amino acid modification in the N-terminus; at least one amino acid modification at position 76; or at least one amino acid modification at position 44 or 89. The modified lectin protein does not consist of the amino acid sequence of any of SEQ ID NOs: 2 to 4.

Abstract: A communication indicating initiation of a payment transaction by a first device is received. Responsive to the initiation of the payment transaction by the first device, a second device is prompted to complete the payment transaction based on the second device corresponding to a user profile associated with the first device. The payment transaction is completed based on the second device facilitating a payment corresponding to the payment transaction.

Abstract: In various example embodiments, a machine is configured to redirect completion of a transaction to a trusted device. For example, the machine determines that a page involving the transaction is being displayed in a user interface of a first device. The page may be associated with the product or service. The machine identifies an interruption of the displaying of the page in the user interface of the first device. The machine identifies a second device that is trusted by the user. The machine transmits a communication including a notification to the second device. The notification indicates the transaction.
