title: A comparative study of procedures for sheep erythrocyte-human-T-lymphocyte rosette formation.
abstract: A comparative study of several published methods for sheep red blood cell-T-lymphocyte rosette formation was performed. Maximum SRBC-rosette formation occurred with AET treated SRBC in medium supplemented with 20% FCS or with untreated SRBC in 100% FCS. Prolongation of the 4 degrees C incubation period from 4 to 18 h enchanced rosette formation. Fluorescein diacetate staining significantly increased calculated percentage of rosette formation. Fluorescein diacetate staining significantly increased calculated percentage of rosette-forming lyphocytes by allowing accurate indentification of the central lymphocytes in morulas.
