FIG. 1.
UV cross-linking of IGF-II leaders 3 and 4 to an RD cytoplasmic extract. An autoradiograph from a UV cross-linking analysis of human IGF-II leader 3 (L3) and leader 4 (L4) in the presence of a detergent-solubilized RD cytoplasmic extract is shown. Cross-linked species and molecular size markers are indicated on the left and right, respectively.
