Patent ID: 6974699

Claim:
A kit of parts comprising a first container and a second container, said first container comprising an antibody molecule conjugated to a first lipase component having a first lipase activity, and said second container comprising a liposome containing one or more pharmaceutically active compound and a second lipase component having a second lipase activity, said first lipase component and said second lipase component reconstituting to form a third lipase component having a third lipase activity, said third lipase activity being greater than the sum of said first lipase activity and said second lipase activity, wherein said first lipase component is a N-terminal recombinant Clostridium perfringens α-toxin (N-CPAT) and said second lipase component is a C-terminal recombinant Clostridium perfringens α-toxin (C-CPAT), said third lipase activity being sufficient to release said one or more pharmaceutically active compound from said liposome when said third lipase component is contacted with said liposome.
