Mj. Gomara et al., Physicochemical characterization of several peptide constructs related with hepatitis A and B viruses, MAT SCI E C, 8-9, 1999, pp. 487-493
lInteraction studies of three different presentations of a continuous B epi
tope of Hepatitis A virus linked to a synthetic T epitope related to Hepati
tis B virus with monolayers composed of dipalmitoylphosphatidylcholine (DPP
C) have been carried out. Surface activity of the peptides was determined a
s a function of its bulk concentration in an aqueous solution. The maximum
pressure achieved at saturation, the molecular area and the surface excess
of the different synthetic peptides were determined. The different physicoc
hemical behaviour of the constructs was dependent on the relative position
of the B and T epitopes. The ability to insert into DPPC monolayers showed
that the highest interaction with phospholipid monolayers corresponded to t
he peptide with the T-cell epitope located at the C-terminus. (C) 1999 Else
