Plasmodium falciparum antigens inducing protective antibodies

摘要

Proteins of peptides (I) which are recognised mainly by cytophilic antibodies (Ab) of subjects protected against Plasmodium infection and by non cytophilic Ab of subjects sensitive to infection are new. Pref (I) is 49kD merozoite surface protein of P falciparum, or a fragment of it, esp the sequence HisGluArgAlaLysAsnAlaTyrGlnLysAlaAsnGln AlaValLeuLysAlaLysGluAlaSerSerTyrAspTyr IleLeuGlyTrpGluPhe(Gly)3Val ProGluHisLysGluGluAsnMetLeuSerHisLeu TyrValSerSerLysAspLysGluAsnIleSerLysGlu AsnGlu (Ia).
