  • Non-peptidic polymeric linker compound, conjugate comprising same linker compound, and methods for preparing same linker compound and conjugate
    Patent number: 11925691
    Abstract: One aspect of the present invention provides a compound in which a functional group capable of binding to a globulin Fc region or a physiologically active polypeptide is introduced at one end of a non-peptidic polymer and a functional group capable of a click reaction is introduced at the other end; a polypeptide conjugate in which a physiologically active polypeptide binds to one end of the compound; a physiologically active polypeptide conjugate in which a physiologically active polypeptide and an immunoglobulin Fc region bind to both ends thereof by using the compound as a linker; and methods for preparing the same compound, polypeptide conjugate, and physiologically active polypeptide conjugate.

  • APPARATUS FOR PREVENTING BREAKAGE OF VARIABLE CHARGE MOTION VALVE LINK
    Publication number: 20160161015
    Abstract: An apparatus for preventing a breakage of a variable charge motion valve link includes a first rod configured to include an insertion hole formed at one end thereof. A second rod is inserted into the first rod through the insertion hole and coupled with the first rod by a fixing pin. When an external force which is equal to or more than a threshold force value is applied to the first rod and the second rod, the second rod is separated from the first rod based on the fixing pin.
