Comparison of the in vitro effects of Lym-2 with chCLL-1 using ALCL cell lines. In these experiments 1 μg/mL of antibody was used with Karpas and Michel ALCL lines being assayed. Lym-2 was immobilized by using a goat-antimouse Ig and chCLL-1 was immobilized by using a goat-antihuman Ig. The data are presented as percent of growth as a percent of control crosslinked mouse or human Ig growth. Representative of two experiments.
