Freeze-drying Process Development for Protein Pharmaceuticals
This chapter provides an overview of the impact of protein formulation variables on different stages of the protein freeze-drying process and offers guidance for selection of critical process parameters during protein freeze-drying cycle development, optimization, and scale-up. There is particular focus on practical considerations including large-scale process development, scale-up challenges, ...
متن کاملCirculating-Gas Freeze Drying
WAGMAN, JACK (U.S. Army Biological Laboratories, Frederick, Md.) AND EDWARD J. WENECK. Preservation of bacteria by circulating-gas freeze drying. Appl. Microbiol. 11:244-248. 1963.-Water-washed Serratia marcescens and Escherichia coli were freeze dried in a circulating-gas system at atmospheric pressure. This convective procedure resulted in a substantially higher survival of organisms than cou...
متن کاملFreeze-drying of Aegyptianella pullorum.
Heparinized whole blood, parasitized with Aegyptianella pullorum, was collected from 2 fowls. Buffered lactose peptone (BLP) was added v/v as a stabilizer and the mixture lyophilized in 2 ml aliquots after rapid or slow freezing. At different stages during the freeze-drying process, as well as after lyophilization and reconstitution with 1.8 ml of sterile water, samples were taken and injected ...
متن کاملEffect of pressure at primary drying of freeze-drying mouse sperm reproduction ability and preservation potential.
Freeze-dried spermatozoa are capable of participating in normal embryonic development after injection into oocytes and thus useful for the maintenance of genetic materials. We recently reported that long-term preservation of freeze-dried mouse spermatozoa by conventional methods requires temperatures lower than -80 degrees C. Successful permanent preservation of mouse spermatozoa at much higher...
متن کاملFreeze-drying of nanoparticles: formulation, process and storage considerations.
Freeze-drying has been considered as a good technique to improve the long-term stability of colloidal nanoparticles. The poor stability in an aqueous medium of these systems forms a real barrier against the clinical use of nanoparticles. This article reviews the state of the art of freeze-drying nanoparticles. It discusses the most important parameters that influence the success of freeze-dryin...
