Pictures of the assembly, dissociation and reassembly of Fe-Por (1.3) gel (brown) with L-His (2.9) gel (red).

a) Fe-Por (1.3) gel and L-His (2.9) gel were placed in a petri dish and an 80 mM Tris-acetate buffer (pH 9.0) was added. b) Agitation for a few minutes led to a gel assembly. c) The addition of L-His solution and agitation led to the dissociation of the gels. d) These gels were washed using an excess of buffer and reassembled by agitation in fresh buffer. Solutions (i) 80 mM Tris-acetate buffer (pH 9.0); (ii) L-His solution added to 80 mM Tris-acetate buffer (pH 9.0).
