FIG. 3.7 – Alkaline dissociation <strong>and</strong> formic acid reassociation of purified Carcinus <strong>maenas</strong> hemocyanin dodecamers<br />

<strong>and</strong> hexamers. Left part, mass spectra for purified dodecamers. Right part, mass spectra for purified hexamers. First row,<br />

purified complexes in 10 mM AcNH4, pH 6.66. Second row, complexes dissociated by addition of 0.03 % TEA (pH 8.55).<br />

Third row, complexes reassociated by addition of 0.0045 % formic acid (pH 7.7). Fourth row, complexes dissociated anew<br />

by the addition of formic acid to a final concentration of 0.065 % (pH
