title: Characterization and quantitation of murine-delayed hypersensitivity responses elicted with particle-associated human gamma-globulin.
abstract: Parameters delineating the utilization of particle-associated human gamma-globulin to quantitate murine-delayed hypersensitivity (DHS) responses include: (1) the conditions used to prepare HGG-coated polystyrene latex particles; (2) the marked increase in sensitivity of detection of delayed immune responsiveness using particle-bound HGG; (3) a histologic analysis of the lesions induced by HGG-latex in DHS mice, and (4) the increased retention of particle-associated as opposed to soluble HGG at the site of challenge. The potential utilization of particle-bound antigens as a sensitive method of assessing the role of delayed-type responsiveness in tumor and transplantation immunity is discussed.
