The present invention is directed to methods for increasing sensitivities of immunoassays. The invention utilizes an acid elution condition that preferentially elute specifically bound immune complexes over non-specifically bound complexes from a solid phase, and designs immunoassay protocols that improve the ratio of specific binding to non-specific binding and thereby improving assay sensitivity. The protocol determines the signal of the labeled immunocomplexes eluted from a solid phase.

Immunoassay with enhanced sensitivity

Transducer assembly for an offshore drilling riser, in an example, includes a spool for connecting into the riser and a protrusion extending around the side wall of the spool. A recess extends around the protrusion between upper and lower sloping surfaces. Upper transducer bores are spaced around the protrusion and extend from the upper sloping surface downward and inward into the spool bore and lower transducer bores extend from the lower sloping surface upward and inward into the spool bore. A base of a rigid non-metallic material is located in each of the transducer bores. A seal ring extends around a cylindrical exterior portion of each of the bases and one of the transducer bores. An acoustic transducer element is mounted to the outer end of each of the bases. The transducer assembly can detect drilling fluid and form sealing.

The present invention provides a fusion protein inhibiting TACI-BAFF complex formation and preparation method therefor and use thereof. Specifically, the fusion protein of the present invention is of high biological activity for blocking BAFF/APPRIL, and may significantly lower the serum IgM concentration in normal Balb/c mice as well as the serum IgM and IgE concentration in C57/B6 mice with asthma. The TACI-Fc fusion protein of the present invention may be used in the treatment of autoimmune diseases, including asthma, systemic lupus eythematosus and rheumatoid arthritis, etc., and may also be used in the treatment of B cell enrichment-related diseases, including multiple myeloma, chronic lymphocytic leukemia, macroglobulinemia and plasmacytic leukemia, etc.

An exemplary motor driving system includes a power source, a driving circuit, a controller, a motor, and a protection circuit. The driving circuit including at least one switching device coupled with the power source. The motor includes a plurality of windings. The motor is coupled with the driving circuit and driven by the driving circuit. The controller is configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode. The protection circuit is coupled with the controller, and configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. A method for operating the motor driving system is also described.
