摘要 |
The present invention provides compositions of Ig fusion proteins, especially compositions including an Ig fusion protein, a bulking agent, a disaccharide, a surfactant, and a buffer. In one aspect, these compositions are stable under long-term storage or at least one freeze/thaw cycle. The invention also provides methods of preparation of the Ig fusion protein compositions. In one aspect, compositions of the invention are lyophilized. In a further aspect, the compositions are lyophilized by a process that includes an annealing step.
