Patent number: 10835606Abstract: 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.Type: GrantFiled: April 15, 2019Date of Patent: November 17, 2020Assignee: Tenboron OyInventors: Anne Leppanen, Filip S.

Patent number: 10513724Abstract: 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.Type: GrantFiled: July 21, 2015Date of Patent: December 24, 2019Assignee: GLYKOS FINLAND OYInventors: Jari Natunen, Anne Leppänen, Heidi Salminen, Jukka Hiltunen, Anne Kanerva, Annamari Heiskanen, Ann Westerholm-Parvinen, Georg Schmidt, Anne Huuskonen, Eero Mustalahti, Christopher Landowski, Markku Saloheimo, Juhani Saarinen, Benjamin Patrick Sommer, Ramon Wahl, Christian Ostermeier, Bernhard Helk
