  • Publication number: 20220378908
    Abstract: The present invention relates to compositions and methods for minimizing protein loss (e.g., due to adsorption to solid surfaces) at low protein concentrations. Inventions disclosed herein generally relate to the field of compositions comprising proteins, in particular, pharmaceutical compositions comprising therapeutic proteins at low protein concentrations. Inventions disclosed herein also relate to methods of administering the composition to a subject in need thereof.

  • Publication number: 20100267936
    Abstract: The present invention concerns a process by which a misfold in an Fc fusion molecule can be prevented or corrected. In one embodiment, the process comprises (a) preparing a pharmacologically active compound comprising an Fc domain; (b) treating the fusion molecule with a copper (II) halide; and (c) isolating the treated fusion molecule. The pharmacologically active compound can be an antibody or a fusion molecule comprising a pharmacologically active domain and an Fc domain. The preferred copper (II) halide is CuCl2. The preferred concentration thereof is at least about 10 mM for fusion molecules prepared in E. coli; at least about 30 mM for fusion molecules prepared in CHO cells. The process can be employed with any number of pharmacologically active domains. Preferred pharmacologically active domains include OPG proteins, leptin proteins, soluble portions of TNF receptors (e.g., wherein the fusion molecule is etanercept), IL-1ra proteins, and TPO-mimetic peptides.
