  • Publication number: 20210106692
    Abstract: The present invention relates to a conjugate represented by the formula [D-L-Y—(CH2)n-]mP-T wherein T is a protein; P is a polymer selected from the group consisting of dextran, mannan, pullulan, hyaluronic acid, hydroxyethyl starch, chondroitin sulphate, heparin, heparin sulphate, polyalkylene glycol, Ficoll, polyvinyl alcohol, amylose, amylopectin, chitosan, cyclodextrin, pectin and carrageenan, or a derivative thereof; m is at least 1; n is in the range of 1 to 10; each Y is independently selected from the group consisting of S, NH and 1,2,3-triazolyl, wherein 1,2,3-triazolyl is optionally substituted; each L is independently absent or comprises a linker group covalently joining D and Y; and each D is a payload molecule.

  • Patent number: 10835606
    Abstract: The present invention relates to a conjugate comprising an anti-EGFR1 antibody or an EGFR binding fragment thereof and at least one dextran derivative, wherein the dextran derivative comprises at least one D-glucopyranosyl unit, wherein at least one carbon selected from carbon 2, 3 or 4 of the at least one D-glucopyranosyl unit is substituted by a substituent of the formula —O—(CH2)”—S—Bi2Hii2? wherein n is in the range of 3 to 10; and the dextran derivative is bound to the anti-EGFR antibody or an EGFR1 binding fragment thereof via a bond formed by a reaction between at least one aldehyde group formed by oxidative cleavage of a D-glucopyranosyl unit of the dextran derivative and an amino group of the anti-EGFR1 antibody or an EGFR1 binding fragment thereof.

  • Patent number: 10513724
    Abstract: The present disclosure relates to compositions and methods useful for the production of recombinant glycoproteins in filamentous fungal cells, such as Trichoderma cells, wherein at least 90% (mol %), preferably at least 95% of the total neutral N-glycans of said produced recombinant glycoprotein are mammalian-like N-glycans. More specifically, the invention provides a filamentous fungal cell comprising i. one or more mutations that reduces or eliminates one or more endogenous protease activity compared to a parental filamentous fungal cell which does not have said mutation(s); ii. a polynucleotide encoding a heterologous catalytic subunit of oligosaccharyl transferase; iii. a recombinant polynucleotide for increasing ?1, 2 mannosidase activity;and, iv. a recombinant polynucleotide encoding said heterologous glycoprotein.
