A method of labelling a cell is provided. Aspects of the method include the contacting the cell with a cholesteryl-cargo conjugate having the formula: C-L-Z (I) wherein C is a cholesterylamine anchor group, L is an optional linker and Z is a linked cargo moiety to non-covalently bind the cholesterylamine anchoring group to the cell membrane thereby displaying Z at the cell surface for an extended period of time. Aspects of the method further include administering the labelled cell to a subject. Also provided is a method of modulating an immune response in a subject and a method of targeting a cell in a subject. Cholesterylamine conjugates, labelled cells and kits including the same that find use in the subject methods are also provided.
提供了一种标记细胞的方法。该方法的方面包括使用具有以下公式的
胆固醇-货物共轭物与细胞接触:C-L-Z(I),其中C是
胆固醇胺锚定基,L是可选的连接物,Z是连接的货物基团,以非共价方式结合
胆固醇胺锚定基到细胞膜上,从而在细胞表面显示Z,并延长其时间。该方法的方面还包括将标记的细胞给予受试者。还提供了一种调节受试者免疫反应的方法和一种在受试者中定位细胞的方法。还提供了
胆固醇胺共轭物、标记的细胞和包括它们的试剂盒,这些试剂盒在上述方法中有用。
