Patent ID: 7754680

Claim:
A peptide reagent having a general structure selected from the group consisting of: a) (CCBD) n ; b) (CCBD x -BA p ) n ; c) (CCBD x -AD y ) n ; d) (CCBD x -TBD y ) n ; e) [(CCBD x -L s ) q -(TBD y -L t ) r ] n ; e) [(CCBD x -L s ) q -(CCBD y -L t ) r ] n ; g) (CCBD x -L-BA) n ; and h) [(CCBD) q -L x -(CCBD) r ] n -L-BA; wherein: i) CCBD is a calcium carbonate-binding domain, comprising a sequence selected from the group consisting of SEQ ID Nos: 204-231; ii) BA is at least one benefit agent; iii) AD is at least one active domain incorporated into a calcium carbonate-binding peptide; iv) TBD is at least one target binding domain incorporated into a calcium carbonate-binding peptide; v) L is a linker molecule; vi) n, p, x, y, q, and r independently range from 1-20; and vii) s and t are each independently 0 or 1, provided that both s and t may not be 0.
