  • Patent number: 10654921
    Abstract: The present invention relates to an antigen-binding protein, preferably a monoclonal antibody, against annexin A2 (ANXA2), comprising (i) a heavy chain variable domain comprising a VHCDR1 of sequence GYSITSGYSWH, a VHCDR2 of sequence YIHYSGSTKYNPSLKS and a VHCDR3 of sequence GSNYGFDY; and (ii) a light chain variable domain comprising a VLCDR1 of sequence KSSQSLLYSNDQKNYLA, a VLCDR2 of sequence WASIRES, and a VLCDR3 of sequence QQYYIYPLT. Also provided is an ANXA2 binding protein comprising (i) a heavy chain variable domain comprising a VHCDR1 of sequence VYSITSGYSWH; a VHCDR2 of sequence YIHYSGSTKYNPSLKS, and a VHCDR3 of sequence GTDNAVDY; and (ii) a light chain variable domain comprising a VLCDR1 of sequence KSSQSLLYSSNQKNYLA, a VLCDR2 of sequence WASSRES, and a VLCDR3 of sequence QQYYIYPLT. The antibodies preferably bind to an N-linked glycan on ANXA2, and are internalised upon binding. They may be conjugated with cytotoxins and may be used in the treatment or detection of cancer.

  • Publication number: 20150217024
    Abstract: Method of manufacturing hydrogel microparticles comprising one or more species of living cells attached thereon and/or encapsulated therein is provided. The method includes dissolving a hydrogel-forming agent in an aqueous medium to form a solution; suspending one or more species of living cells in the solution to form a cell suspension; dispersing the cell suspension into an organic oil to form a microemulsion; and subjecting the microemulsion to conditions that allow the hydrogel-forming agent to form hydrogel microparticles comprising one or more species of living cells attached thereon and/or encapsulated therein. Composition comprising a mixture of a degradable hydrogel and at least one hydrogel microparticle having one or more species of living cells, and method of manufacturing a scaffold for tissue engineering are also provided.
