ABSTRACT
Limulus Factor C, a serine protease zymogen from the amoebocytes of the limulus, has high affinity for endotoxin. When Factor C is activated by endotoxin, it hydrolyses artificial tripeptide substrate and measurable products are released, so it can be used as an alternative reagent for endotoxin analysis. Factor C gene of Tachypleus tridentatus was obtained through RT-PCR and the recombinant protein was expressed by Bac-to-Bac/BmNPV baculovirus expression system in silkworm larvae. The activity of Factor C was detected with diluted serum of silkworm larvae, and the sensitivity of endotoxin detected was 0.2 EU/mL when the serum was diluted at 1500. The silkworm larvae expressed limulus Factor C could be used to develop a new low-cost endotoxin test reagent.
