Abstract: 1) On electrophoretic separation, a total of 5 protein bands were detected in the Balanus nubilis blood. 2) Three of the proteins present in B. nubilis blood showed peroxidase activity. Because of tests performed on the fastest of these proteins and absorption spectra obtained for the whole blood, this fast protein is assumed to be hemoglobin. 3) Molluscan hemocyanins migrate much slower than Crustacean hemocyanins and, in some species, split up into electrophoretic "fast" and "slow" components. [note: original text obscured at this point] ...respiratory pigments consistently showed strong peroxidase activity.
