Freeze-Drying To Produce Efficacious CPMV Virus-like Particles

Circulating-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...

Avian lymphoid leukosis: Virus-like particles in kidney Cells

Foot-and-mouth disease virus: stability of neutralizing antibody after freeze-drying and air-drying.

It is possible to stabilize foot-and-mouth disease antiserum by either freeze-drying in bottles or air-drying on paper for periods of 7 months.

Sperm 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...

Freeze-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)...
