Abstract
Sea-urchin fibronectin from the ovary of the sea urchin Pseudocentrotus depressus bound to gelatin, fibrin and fibrinogen. After mild digestion of the protein labelled with 125I, a 195 000 Da domain was observed. Sea-urchin fibronectin was aggregated by spermine (1 mM) at neutral pH. When the concentration of spermine was decreased or increased, the aggregation was diminished. The addition of 1 M-NaCl or 4 M-urea inhibited the spermine-induced aggregation. Sea-urchin fibronectin mediated the spreading of baby-hamster kidney cells on the plastic surface.This publication has 16 references indexed in Scilit:
