Abstract

Delayed-type hypersensitivity (DTH) is an in vivo assay of cell-mediated immune function. DTH reactions are often divided into two phases: the sensitization phase, referring to the initial immunization with specific antigen, and the efferent or challenge phase of the DTH response, which usually follows 6 to 14 days after sensitization. This unit details the protocol for stimulating DTH responses in mice to the O-succinimide ester of the hapten 4-hydroxy-3-nitrophenyl acetyl (abbreviated NP-O-Su).
