Preservation of enteroviruses by freeze-drying.
A method was developed for freeze-dry stabilization of poliovirus type 3. An ultrafiltration procedure was used to remove salts from infected tissue culture fluid, and the virus was freeze-dried after suspension in an alkaline organic buffer. This method was further tested with other picornaviruses including poliovirus types 1 and 2, coxsackieviruses A9, A20, B2, and B5, echovirus 11, and the e...

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 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 کاملSperm freeze-drying; effects on sperm parameters
Today, sperm cryopreservation is a routine practice in infertility clinics. One of the alternative methods to preserve sperm is freeze-drying. This process consists of three steps. The first step is sample freezing, during which the solvent is separated from the solvent. Water forms ice crystals and the solute is placed between the ice crystals. Freezing may be done in a separate device or in a...
متن کاملFreeze-drying above room temperature.
This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...
