Rate constants for the hexamer-dodecamer reaction of lobster hemocyanin

90° stopped-flow light scattering experiments have been used to determine the forward and reverse rate constants of the reversible hexamer-dodecamer reaction of lobster hemocyanin in glycine buffer at pH 9.6. Results were obtained at 20.5° and 25° at two different levels of calcium ion, and equilibrium constants derived from the data are in good agreement with those measured earlier with the ultracentrifuge.
