    摘要: The present invention relates to a method of immobilizing a cell on a support, the method comprising a) providing a compound or salt thereof comprising, preferably consisting of, one or more hydrophobic domains attached to a hydrophilic domain, wherein the one or more hydrophobic domains are covalently bound to said hydrophilic domain, and wherein the one or more hydrophobic domains each comprise a linear lipid, a steroid or a hydrophobic vitamin, and wherein the hydrophilic domain comprises a polyethylene glycol (PEG) moiety, and wherein the compound comprises a linking group; b) contacting a cell with the compound under conditions allowing the interaction of the compound with the membrane of the cell, thereby immobilizing the linking group on the surface of the cell; and c) contacting the linking group immobilized on the cell with a support capable of binding the linking group, thereby immobilizing the cell on the support.
