84METHANOL AS A CRYOPROTECTANT FOR EQUINE EMBRYOS

Cryopreservation of common carp (Cyprinus carpio) embryos using different cryoprotectant

This study reports that common carp (Cyprinus carpio) embryos were successfully frozen and preserved by vitrification. The modified Haga solution was tested by using two different cryoprotectants and three different concentrations at 4°C to obtain appropriate vitrified solutions ((dimethylsulfoxide 5, 10, 15% (DMSO) and glycerol 5, 10, 15% (gly)) in the study.  The hatching rates of embryos exp...

How to Evaluate Equine Embryos

Cryopreservative solution using rakkyo fructan as cryoprotectant

Introduction Cryopreservation of the cells allows great flexible application for cell therapy, as well as industrial production of biologics such as antibody therapeutics. Conventionally, cryopreservative solution contains both of fetal bovine serum (FBS) and dimethyl sulfoxide (DMSO) as a cryoprotectant [1]. However, both of them have problems. FBS frequently induces differentiation of stem ce...

Use of methanol as cryoprotectant and its effect on sox genes and proteins in chilled zebrafish embryos.

Methanol is a widely used cryoprotectant (CPA) in cryopreservation of fish embryos, however little is known about its effect at the molecular level. This study investigated the effect of methanol on sox gene and protein expression in zebrafish embryos (50% epiboly) when they were chilled for 3 h and subsequently warmed and cultured to the hatching stages. Initial experiments were carried out to...

Title: 1 SHORT TERM CHILLED STORAGE OF ZEBRAFISH (Danio rerio) EMBRYOS IN 2 CRYOPROTECTANT AS AN ALTERNATIVE TO CRYOPRESERVATION

23 As zebrafish embryos never been cryopreserved, we developed a protocol to store zebrafish embryos 24 (50% epiboly5.3 hpf) for up to 18 h at 0° C. Initial experiments to optimise cryoprotectant solution 25 demonstrated improved embryo hatching rate following chilling at 0°C for 18 h with 1 M MeOH + 26 0.1 M sucrose (56 ± 5%) compared to other combination of methanol (0.2-, 0.5 M) and sucrose ...
