  • Publication number: 20180003711
    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 permeabilized 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.

  • Patent number: 9631974
    Abstract: The invention relates to a photoarray (1), comprising: a plurality of cells (10), wherein each of said cells (10) comprises a means (20)that is configured to generate a photocurrent (I) being proportional to the intensity (L) of the light impinging on the respective cell (10), and wherein each of said cells (10) comprises a change detection circuit (100) connected to the respective means (20) for generating the photocurrent (I), which change detection circuit (100) is configured to generate an output signal merely in case a change event occurs at which said intensity (L) changes by a threshold amount (T, T?) since the preceding change event from the respective cell (10). According to the invention said means (20) for generating said photocurrent (I) is additionally also used to estimate the magnitude of the said photocurrent (I) being a measure of the brightness of the light at the respective cell (10).

  • Publication number: 20160324947
    Abstract: The invention relates to lipopeptides consisting of a peptide chain comprising a parallel coiled-coil domain, a proline-rich peptide antigen, and a lipid moiety, all covalently linked, which aggregate to synthetic virus-like particles. Proline-rich peptide antigens considered contain negatively and positively charged amino acid, and at least 15% of the amino acids are proline. Such synthetic virus-like particles carrying proline-rich antigens derived from pneumococcal proteins are useful as vaccines against infectious diseases caused by Gram-positive bacteria such as Streptococcus pneumoniae.
