Abstract
The present invention relates to a method and device for the in vitro testing of potential nematicidal and nematistatic agents, comprising treatment of nematodes with test substances, followed by assessment of the ability of the treated nematodes to move through a chemattractant gradient set up on a coated solid support, said coating comprising a gellable polymeric substrate incorporating a stabilizing agent.
Claims18
A device for the detection of nematode vitality comprising:
- (a) a solid surface having a coating, said coatign comprising a mixture of a gellable polymeric substrate and an assay stabilizing salt;
- (b) said coating also containing, at particular areas, concentration gradients of a chemaatractant inorganic salt, wherein the anions of said assay stabilizing salt and of said chemattractant inorganic salt are identical.
