N2 - Binding to the midgut microvillar surface in the sandfly Phlebotomus papatasi is a prerequisite for successful development of Leishmania major within the gut of the vector. This paper describes a method for detecting microvillar-associated proteins which act as ligands for the parasite surface glycoconjugate lipophosphoglycan (LPG). Adhesion of LPG to midgut proteins was visualized by probing midgut extracts with LPG using a Western ligand blotting technique. Procyclic L. major LPG bound to a microvillar polypeptide band of 65 kDa (estimated in the non-reduced state) and bound variably to several lower molecular weight bands, probably degradation products or subunits of the primary binding polypeptides. Specificity of binding was confirmed by co-incubating biotinylated LPG with an LPG-specific mAb which resulted in a great reduction in binding.
