Patent ID: 8425900

Claim:
A micelle-protein complex comprising: a micelle of a cationic polymer, the cationic polymer having a structure of general formula I: —(W—X—Y—Z) p —(W′—X′—Y′—Z′) q —; and a protein, the protein having a region available to complex with the micelle; the protein complexed to the exterior of the micelle via an interaction between the protein and the polymer; wherein, in general formula I: each of W, X, Y and Z is independently selected from nothing, wherein only one of W, X, Y and Z is nothing and at least one of W, X, Y and Z is a group containing nitrogen bonded to R or R′; each of W′, X′, Y′ and Z′ is independently selected from and nothing, wherein only one of W′, X′, Y′ and Z′ is nothing, and at least one of W′, X′, Y′ and Z′ is a group containing nitrogen bonded to R″ or R′″; each of R and R′ is independently H, alkyl or heteroalkyl; each of R″ and R′″ is independently a hydrophobic group; each of p and q is independently an integer greater than zero; and each of m, n, r, s, t, m′, n′, r′, s′ and t′ is independently an integer greater than 0.
