Lipase from Rhizopus sp. has been immobilized covalently on tresyl activated silica. Three different coupling media were evaluated: aqueous buffer, n-hexane, and a microemulsion based on n-hexane, aqueous buffer, and the nonionic surfactant triethylene glycol monododecyl ether. In addition, coupling via a very long, hydrophilic spacer arm, polyethylene(More)
Injection of antibodies to Ca-binding protein S-100 in a dilution of 10(-12) before the formation of long-term sensitization in Helix lucorum (10 min before the first electric shock) prevented the increase in defense reactions of pneumostome closure and ommatophore withdrawal. Thus, we demonstrated a protective effect of low-dose antibodies to S-100 on the(More)
