FIG. 1.

Binding of ¹²⁵I-mBSA to peritoneal Mφ. Mφ were preincubated on ice for 20 min with binding buffer alone or supplemented with additives as indicated, before the addition of 5 × 10⁵ cpm of ¹²⁵I-mBSA. Results are expressed as the mean specific binding (and 1 standard error) of ¹²⁵I-mBSA in triplicate samples as described in Materials and Methods.
