  • Publication number: 20170184593
    Abstract: This invention publicizes a chronic renal disease diagnostic kit, comprised of FGF23 monoclonal antibody, biotin labeling reagent Sulfo-NHS-LC-Biotin, PBS buffer solution (pH7.0, 0.1M), casein saline solution, streptomycin avidin and substrate TMB. The labeling condition is the weight ratio of FGF23 antibody and Sulfo-NHS-LC-Biotin, which is 1:5-1:12. The dilution ratio of streptomycin avidin is 1:3000. The lowest testing threshold limit value of FGF23 kit is 10 pg/ml, whose sensitivity is 10 times higher than that of common monoclonal antibody, which is very significant for early diagnose of chronic renal disease.

  • Patent number: 9634540
    Abstract: A magnetic suspension planar motor comprises a structure of superconductor excitation. A primary base plate is in a shape of board. Armature windings are fixed on an air gap side of the primary base plate. A secondary base plate in a secondary structure is evenly divided into 2 h*2 h magnet cells. 2 h2 superconducting magnets are respectively fixed in the magnet cells on the secondary base plate, which resembles a checkerboard pattern. The superconducting magnets are adjacent to each other, neither in a horizontal direction nor in a vertical direction. The superconducting magnets are magnetized parallelly, and magnetization directions of the superconducting magnets are perpendicular to a surface on an air gap side of the secondary base plate. The superconducting magnets in a same row or column have same magnetization directions, and the superconducting magnets in adjacent rows columns have contrary magnetization directions. A cooling container shields all of the superconducting magnets.
