An electro-mechanical method for measuring delayed hypersensitivity in mice by increase of ear thickness.
An electro-mechanical modification of a micrometer gauge for measurements of mouse ear thickness is described. Its advantages are objectivity and speed of operation. The instrument is useful for measuring delayed hypersensitivity reactions to oxazolone and picryl chloride in mice.
