  • Publication number: 20240069018
    Abstract: The invention relates to a method for selecting an expressed sequence from a library, comprising the following steps: Each of a plurality of eukaryotic cells comprising a cell wall comprises a nucleic acid sequence member of a library, which is expressed as a target membrane protein in said eukaryotic cells. The cell wall of the cells is permeabilized. The penneabilized cells are labeled with a ligand capable of binding to the target membrane protein. The ligand bears a detectable label. A subset of the labelled cells is selected as a function of detectable label present. Finally, an expressed nucleic acid sequence is isolated from said selection of cells in an isolation step.

  • Publication number: 20230212340
    Abstract: The present invention relates to a contrast agent suitable for ex vivo imaging, particularly of vascular structures and renal tubular structures, and a method for ex vivo imaging. The contrast agent is a polymer comprising monomers M. The monomer comprises a backbone having 2 to 6 elements, wherein at least one element is —CH(R)— or —N(R)—. R is a moiety -E-H, -L-(NH2)m or a moiety of formula 1, with E, L, R1 and R2 being defined as described in the present specification. The monomer comprises at least one —I to allow detection via X-ray and at least one —NH2 to allow crosslinking. Furthermore, the monomer comprises polar functional groups that contribute to water solubility. To avoid extravasation and glomerular filtration, the polymers are pre-crosslinked before the vasculature of a tissue, an organ or whole animal is perfused. After perfusion, the pre-crosslinked contrast agent is further crosslinked to be retained within the tissue, organ or animal permanently.
