3 The association constant for formation of the complex between labeled TNC (TNC*) and TNI was 6.67 X 10(5) M-1 in 0.3 M KCl, and pH 7.5 at 20 degrees C. In the presence of bound Mg2+, the binding constant increased to 4.58 X 10(7) M-1 and in the presence of excess of Ca2+, the association constant was 5.58 X 10(9) M-1. Potassium Chloride tenascin Oryctolagus cuniculus
