[Research Advance on Preparation Technology and Application of Virus-inactivated Lyophilized Plasma---Review]

Lyophilized plasma has a certain advantage in emergency situation, such as war wound treatment. However, lyophilized plasma has two major problems, plasma pathogen pollution and mass loss after lyophilized. Studies have shown that plasma pathogen inactivation technology targeting pathogen envelope or nucleic acid can ensure its safety, and adding citric acid and glycine to plasma can effectively maintain pH and protein activity of plasma after reconstitution. At present, there are three kinds of lyophilized plasma products on the market abroad, but none for China. Therefore, understanding the research progress of lyophilized plasma may contribute to the development of similar products in China.
