Abstract

The present in invention relates to a method for the separation of living cells from a mixture of dead and living cells which optionally can also possibly contain cell fragments.

Claims (8)

1. A method for the separation of living eukaryotic cells from dead eukaryotic cells, comprising contacting a mixture comprising the living eukaryotic cells and the dead eukaryotic cells with a matrix material comprising a poly(methyl vinyl ether-alt-maleic acid):

that is able to form a polyanionic structure, wherein the dead eukaryotic cells adsorb onto the matrix material and the living eukaryotic cells do not adsorb onto the matrix material.

2. The method according to claim 1 , wherein the matrix material is present in a solid state on a wall of a reaction vessel or a dipstick.

3. The method according to claim 2 , wherein the matrix material is present in a liquid or disperse state prior to separation and after separation is fixed or adsorbed to the reaction vessel or dipstick, or is present in precipitated or suspended form.

4. The method according to claim 1 , wherein the poly(methyl vinyl ether-alt-maleic acid) has been esterified to a partial alkyl ester.

5. The method according to claim 1 , wherein the reaction vessel is a Petri dish, a cell culture dish, a multi-well plate, a cell culture bottle or blocks.

6. The method of claim 4 , wherein the poly(methyl vinyl ether-alt-maleic acid) has been esterified to a C 1 -C 6 alkyl ester.

7. The method of claim 6 , wherein the poly(methyl vinyl ether-alt-maleic acid) has been esterified to a methyl ester.
