  • Publication number: 20240117068
    Abstract: The present invention concerns antigen binding proteins specifically binding melanoma associated antigen A (MAGE-A) protein-derived antigens. The invention in particular provides antigen binding proteins which specifically bind to the MAGE-A antigenic peptide comprising or consisting of SEQ ID NO: 1 in a complex with a major histocombatibility (MHC) protein. The antigen binding proteins of the invention contain, in particular, the complementary determining regions (CDRs) of novel engineered T cell receptors (TCRs) that specifically bind to said MAGE-A peptide/MHC complex. The antigen binding proteins of the invention are of use for the diagnosis, treatment and prevention of MAGE-A expressing cancerous diseases. Further provided are nucleic acids encoding the antigen binding proteins of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen binding proteins and pharmaceutical compositions comprising the antigen binding proteins of the invention.

  • Publication number: 20230088952
    Abstract: A process can be used for preparing a polymer coated hard-shell capsule, filled with a fill containing a biologically active ingredient. The hard-shell capsule contains a body and a cap, and in a closed state, the cap overlaps the body either in a pre-locked state or in a final-locked state. The material of the body and the cap contains an ethyl-, methyl-, or propyl-ether of cellulose, starch, or pullulan. The hard-shell capsule is coated with a coating layer that covers the hard-shell capsule in the pre-locked state. The coating layer contains one or more (meth)acrylate copolymers, where the coating layer is present in an amount of about 1 to 5.8 mg/cm2. The process involves providing the polymer-coated hard-shell capsule in the pre-locked state to a capsule-filling machine, separating the body and the cap, filling the body with the fill, and rejoining the body and the cap in the final-locked state.

  • Publication number: 20220226865
    Abstract: A monitoring device of a conveying system for comminuted materials includes at least one measuring apparatus, by which at least one substance component can be detected in the comminuted materials. Further, a conveying system and a method for monitoring comminuted materials are provided. At least one monitoring region, in which the content of at least one substance component in a comminuted material can be determined by at least one measuring apparatus, while the comminuted materials are being conveyed, covers at least one portion of a conveying path of the conveying system. At least one rejection apparatus is arranged downstream of at least one monitoring region on the conveying path in the direction of conveyance of the comminuted materials. Via such a device, the comminuted materials can be rejected if the content of the at least one substance component determined by the at least one measuring apparatus exceeds a predetermined threshold value.

  • Publication number: 20200222908
    Abstract: A device for separating material composites to be disposed of, including at least two material fractions with differing material properties, and a method for separating such material composites are provided. The device, in a region of an upper cover plate, has a bowl-shaped dispensing channel having at least one opening facing toward an impact chamber, and a dispenser arranged in the channel and designed to receive material fractions of a second type from the region of the chamber above a first separating screen and/or near the upper cover plate. Individual material fractions of a material composite, such as a material fraction of the second type to be comminuted and having a lower density than a first material fraction, may be separated in larger pieces from remaining material, to facilitate the transport of individual material fractions and further processing as part of raw material recovery.
