All labeling was completely inhibited in the presence of a 100-fold excess of the appropriate unlabeled cytokine.

Abbreviation: nd, not determined.

Determined by Scatchard analysis on 5 × 10⁶ C57BL/6 BM cells incubated on ice for 3 hours.

Mean grain counts ± standard deviations of labeled cells.
