Figure options MgCl2 concentrations between 0 and 5 mM did not induce significant modifications of [125I][1DMe]Y8Fa binding [Fig. 1(B)]. A mixture of 10 mM NaCl and 1 mM MgCl2 did not significantly increase [125I][1DMe]Y8Fa binding compared to that a<a href='http://www.ubiquitin-specific-protease-3-f
