Figure 4: Competition of C19jun and bFGF for 125I-bFGF binding to FGFR1.
From: Semirational design of a potent, artificial agonist of fibroblast growth factor receptors

125I-bFGF was incubated with FGFR1 immobilized on microtiter plates in the presence of the indicated concentrations of C19jun or unlabeled bFGF, washed extensively, and the total amount of radioactivity bound was determined as described in Experimental Protocol.
