| 摘要 |
The invention relates, firstly, to a biomolecule-releasing cell characterized by a surface protein with an extracellular exposed ligation peptide sequence for enzymatic conjugation of an adapter ligand, said adapter ligand being suitable for the indirect or direct coupling of a molecular catching structure which has at least one specific binding site for the released biomolecules, wherein the catching structure is at a distance from the specific binding site, secondly, to a method for selecting such a cell, and thirdly, to a means for this method comprising the surface protein that is characterized by an extracellular exposable ligation peptide sequence for enzymatic conjugation of an adapter ligand, a nucleic acid coding for the surface protein, an expression vector for the nuclei acid, and a cell containing the expression vector. |
