Phenoloxidase forms of the Florida spiny lobster: Immunological and spectropolarimetric characterization

1. 1. In vivo activation of cuticular phenoloxidase (PO) of Florida spiny lobster is apparently mediated by some mechanism other than tryptic activity. 2. 2. Endogenously activated (EAPO) and trypsin activated (TAPO) forms of Florida spiny lobster PO show differences in their secondary structure as evidenced by circular dichroism spectropolarimetry. 3. 3. EAPO and TAPO forms of Florida spiny lobster possess identical antigenic determinants.
