| Abstract: | Summary Microencapsulation of insect cells, hosts for baculovirus expression systems, requires that the encapsulation reagents and membrane-forming materials be non-toxic to the cells. Various encapsulation polymers (poly-l-lysine, chitosan and alginate) and solutions (KCl, CaCl2, CHES and sodium citrate) were tested for their toxicity toSpodopterafrugiperda cells. The effects of varying polymer molecular weight and concentration on cell viability were also investigated. |
