Method and apparatus for introducing substances into the cell plasma membrane and/or cytosol

摘要

There is disclosed a method for introducing agents into the cytosol and/or plasma membrane of a cell. The method comprises the steps of: (a) coating at least a portion of a tip of a transferring means with a lipid; (b) bringing the lipid-coated tip of the transferring means into contact with the cell; and (c) transferring the contents of the transferring means into the cytosol and/or plasma membrane of the cell without entering the cytoplasm. Also disclosed is a transferring means for injecting agents into the cytosol and/or plasma membrane of the cell and a method of coating a tip of a transferring means with a lipid. A suitable packaging and a method for preparing the transferring means for use are also disclosed.
