Abstract: This invention relates to a fusion protein comprising at least one first portion (I) comprising a trafficking sequence and at least one second portion (II) comprising a full-length or partial BH3-domain sequence of a BH3-only protein, said fusion protein comprising D-enantiomeric amino acids in retro-inverso order in its portion (I). Furthermore, the invention relates to pharmaceutical compositions containing said fusion protein as well as to the use of said fusion protein.

Abstract: The present invention features a method for preparing superparamagnetic iron particles by the in situ formation of these particles in a cross-linked starch matrix or by the formation of a superparamagnetic chitosan material. The superparamagnetic materials are formed by mild oxidation of ferrous ion, either entrapped into a cross-linked starch matrix or as a chitosan-Fe(II) complex, with the mild oxidizing agent, nitrate, under alkaline conditions. The present invention further features superparamagnetic iron compositions prepared by the method of the invention. The compositions of the invention are useful for the separation, isolation, identification, or purification of biological materials.
