ABSTRACT:
The use of CCH-A subunit isolated from hemocyanin of the marine gastropodConcholepas concholepas(CCH), or a combination thereof, as an immunostimulant agent in the innate or adaptive immune response of vertebrates or as an immunotherapeutic agent in cancer of either humans or animals, where the CCH-A subunit has a molecular weight of about 404 kDa, is stable in the absence of Ca+2and Mg+2and is at least 95% pure.
