Method for applying solutions with different active material concentrations to live cells comprises feeding solutions to position near application site and mixing them in ratio producing solution of desired final concentration
Method for applying solutions with different active material concentrations to live cells comprises feeding solutions to position near application site and mixing them in ratio producing solution of desired final concentration
Method for applying aqueous solutions with different concentrations of active material to live cells or isolated membrane patches of cells comprises feeding at least two solutions of different concentration to a position near that where application is to be carried out and mixing them in a ratio which gives a final solution of the desired concentration. An independent claim is included for apparatus for carrying out the method which comprises precision syringes (1, 2) containing the starting solutions (3, 4). These are connected by steel pipes (5, 6) to a microscopically small mixing chamber (8) near the application site (7) and pumps (13, 14) are connected upstream from the syringes which can be controlled to give a precise flow speed for the solutions.
