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...

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 as an alternative method of human sclera preservation.
PURPOSE To compare the effect of preserving sclera samples in either 95% ethanol or freeze-dried. METHODS Ninety-six samples of human sclera were studied. Half of them were freeze-dried and half preserved in 95% ethanol. Preservation periods of 18, 45, 90 or 174 days were studied. Automated immunostaining was carried out in the Ventana BenchMarkR LT platform using collagen 1 and fibronectin a...
متن کاملPreservation of Lactic Acid Bacteria by Freeze-Drying
Lactic acid bacteria are widely used in the manufacture of fermented milk products, such as cheeses, sour cream butter, yoghurt and fermented milk beverages. These microorganisms may also be applied to the production of fermented meat products and silage. We may easily cultivate lactic acid bacteria in milk. However, it is a laborious work to preserve the organisms in liquid state because viabi...
