[Development of a highly efficient method for separating bee venom components].

Factors preventing complete separation of melittin and phospholipase A2 under fractionation of the bee venom were studied. The methods of electrophoresis in PAAG, gel-filtration, ion-exchange and reverse-phase chromatography were used to show that the intermolecular interactions of suppositionally hydrophobic character prevent from complete separation of melittin and phospholipase A2. Conditions and methods are chosen which permit isolating melittin and phospholipase in a pure form.

[Interaction between bee venom melittin and human blood albumin].

It is shown that bee venom melittin interacts with human blood albumin at pH 8.0-8.5 in the presence of NaCl (concentration over 0.1%) and forms a precipitating complex (MA), the albumin/melittin ratio being 1:12 for the monomer melittin. With a decrease of pH down to 5.3 and salt concentration below the limit mentioned, the precipitate is destroyed. The complex is soluble in the distilled water. Conditions for carrying the precipitation reaction between albumin and melittin in agarose gel are chosen. The titration method has been used to determine that melittin is bound up with albumin in the molar ratio (10-12):1 for monomeric melittin or 3:1 for tetrameric melittin.
