rbhIL-2 binding is specific for activated lymphocytes. PBMC were incubated in the presence or absence of PHA and subsequently labeled with rbhIL-2-SA-FITC conjugates as described in Materials and Methods. (A) Dot plot indicating the lymphocyte population gated on for analysis of rbhIL-2-SA-FITC binding. (B) Histogram representing gated lymphocytes and rbhIL-2-SA-FITC binding after incubation in the absence of PHA. (C) Histogram representing gated lymphocytes and rbhIL-2-SA-FITC binding after incubation in the presence of PHA.
