Bee venom is a rich source of pharmacologically active substances. In this study, we identified a bumblebee (Bombus ignitus) venom Kunitz-type serine protease inhibitor (Bi-KTI) that acts as a plasmin inhibitor. Bi-KTI showed no detectable inhibitory effect on factor Xa, thrombin, or tissue plasminogen activator. In contrast, Bi-KTI strongly inhibited(More)
Bee venom contains a variety of peptides and enzymes, including serine proteases. While the presence of serine proteases in bee venom has been demonstrated, the role of these proteins in bee venom has not been elucidated. Furthermore, there is currently no information available regarding the melanization response or the fibrin(ogen)olytic activity of bee(More)
Although, classical swine fever virus (CSFV) envelope glycoprotein E2 subunit vaccine has been developed using the baculovirus expression system, the expression of viral antigens in baculovirus-infected insect cells is often ineffective. Therefore, an alternative strategy to the traditional baculovirus expression system is needed that is more productive and(More)
