Abstract: A carrier which may have excellent pressure resistance, and even when a protein ligand is not immobilized thereon, a high dynamic binding capacity to a target substance, and a high performance of separating a target substance from a biological sample. Such a carrier may include a polymer having a crosslinked structure containing a divalent group of formula (1): wherein R1 to R4 are independently a single bond or divalent hydrocarbon group, R5 and R6 are independently H or a hydrocarbon group, X is a thio group, sulfinyl group, sulfonyl group, oxy group, >N(—R31), >Si(—R32)2, >P(—R33), >P(═O)(—R34), >B(—R35), or >C(—R36)2 (R31 to R36 independently being H or hydrocarbon group), and * is a bond, provided that when both R1 and R3 or both R2 and R4 are a divalent hydrocarbon group, respectively, R1 and R3 or R2 and R4 may form a ring together with an adjacent carbon atom.

Abstract: The present disclosure relates to the detection of analytes in high volumetric flow applications. Particular embodiments relate to the use of fluorescence polarization/anisotropy based for detection of analytes in a flow cell. In one testing format, an analyte of interest is probed with reagents containing fluorescent labeled recognition elements. When present in a sample or portion of a sample, the labeled analyte produces a shift in fluorescence polarization/anisotropy/intensity/lifetime as the output signal following the binding of the recognition elements to the analytes.

Abstract: The present invention provides methods to identify and quantify empty, partial and full capsids. The capsids can be purified from a crude AAV sample using affinity chromatography and eluted from the solid support. The purified capsids can then be subjected to density gradient equilibrium analytical ultracentrifugation (DGE-AUC) for characterization and quantitation of capsid content.

Abstract: A two-step chromatography purification scheme is described which selectively captures and isolates the genome-containing rAAV vector particles from the clarified, concentrated supernatant of a rAAV production cell culture. The process utilizes an affinity capture method performed at a high salt concentration followed by an anion exchange resin method performed at high pH to provide rAAV vector particles which are substantially free of rAAV intermediates.

Abstract: Systems and devices for producing biological products and methods of using the same are provided. An example universal skid includes a rigid support and a plurality of flow-channel hardware sets. Each flow-channel hardware set couples with a respective flow channel of a plurality of flow channels for unit operations. The flow-channel hardware sets allow the flow channels to operate in parallel or in series for continuous processing over the unit operations. An example modular assembly includes one or more single-use kits for one or more unit operations and a universal skid coupled with the one or more single-use kits. An example manufacturing system includes multiple modular assemblies coupled with each other allowing continuous processing within each modular assembly, in between the modular assemblies, fully continuous processing across multiple unit operations.
