high purity trehalose Applications :
In Medical Industry Trehalose is widly used in these following fields
◆. High purity trehalose trehalose has been successfully applied to blood products such as vaccine, lymphocyte and other cytokines to stabilize their activities. Trehalose can not only be conserved at an ambient temperature, but also prevent some vital disease such as hepatitis B and AIDS caused by contaminated blood resource from transforming.
◆..Quadrant Research Fund Association, England, found that vaccines and other temperature-vulnerable biologicals which usually require cold storage at 4 ℃ is stable at 45℃ after mixture with trehalose. Thus, the cost of storage and transportation will be greatly decreased while maintaining high potential of vaccine undergoing a far distance transportation.
◆..In California, America, John Calau and his collegues has successfully applied trehalose to preserve blood platelet by dehydrating cells and hyophilization, and the platelet can be preserved for a long time at an ambient temperature and showed survival percentage of 85%.
◆.. High purity trehalose can be used to keep biological agents such as enzyme, cell membrane, organelle, antibody and virus, and make life-science research more convenient, rapid and effective. Research on the protective function of trehalose on restriction enzyme, DNA ligase and DNA polymerase has been carried out, and results showed that all enzyme samples with addition of trehalose, kept 35 days at 70℃ or 9 months at 37℃, maintained nearly 100% of their original activities. The Chinese scientists tested three diagnostic enzymes which were prepared with trehalose as disccant to assay human serum cholesterol, and found that trehalose could keep 90% of their activity after long-term storage at an ambient temperature.
◆.. Using trehalose as lyophilization protectant can efficiently retain activity of vaccine for domestic animals and poultry and virus-vaccine for man, for example, attenuated hepatitis A virus vaccine, epidemic encephalitis B vaccine. And the inoculated efficiency of vaccine can be kept without low temperature storage and freezing transportation.
