This human antibody &kgr; type light chain complex-containing composition comprises a complex in which a human antibody &kgr; type light chain is bound to one type or more of a metal ion selected from the group consisting of Group 10 elements, Group 11 elements and Group 12 elements. The human antibody &kgr; type light chain is a dimer, cysteines at the C terminal of the two human antibody &kgr; type light chains are bound via the metal ion, and 0.1 mol or more of the metal ion is bound per 1 mol of the human antibody &kgr; type light chain. |
