Effects of cryoprotectant concentration and cooling rate on vitrification of aqueous solutions

, 2006
Vitrification of aqueous cryoprotectant mixtures is essential in cryopreservation of proteins and other biological samples. We report systematic measurements of critical cryoprotective agent (CPA) concentrations required for vitrification during plunge ...

Microprocessor-controlled vs. "dump-freezing" platelet and lymphocyte cryopreservation: A quantitative and qualitative comparative study [PDF]

, 2006
Background/Aim. Thermodynamical and cryobiological parameters responsible for cell damages during cryopreservation (cryoinjuries) have not yet been completely explained. Thus, freezing procedures should be revised, exactly optimized to obtain an enhanced

Toxicity of cryoprotective agents at 30°

Journal of Pharmacy and Pharmacology, 1968
Abstract The toxicity of four cryoprotective agents (glycerol, dimethylsulfoxide, dextran, magnesium ion) as a function of time was assessed at 30° on isolated rabbit atria. Glycerol, 2·0 M, in Ringer solution killed all atria in less than 30 min. Atria tolerated 2·1 M dimethylsulphoxide in Ringer for 1 hr, 0·7 M glycerol in Ringer for 4

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Clinical grade vitrification of human ovarian tissue for fertility preservation [PDF]

, 2013
Cryopreservation of human ovarian tissue is one approach to preserve fertility for women who can be predicted to undergo premature ovarian failure as a consequence of chemotherapy, radiotherapy or genetic disorders. It is the most suitable option for pre-

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...
