title: Bioassay for thymic extracts: guinea pig spleen lymphocytes-rabbit red blood cells rosette method.
abstract: An assay is described for assessing the potency of thymic extracts by the capacity of guinea pig spleen lymphocytes to form rosettes with rabbit red blood cells. Its sensitivity and reproducibility have been evaluated by statistical analysis of the data obtained testing different batches of the calf thymus extract TP-1.
