Figure 2From: Participation of heparin binding proteins from the surface of Leishmania (Viannia) braziliensis promastigotes in the adhesion of parasites to Lutzomyia longipalpis cells (Lulo) in vitroQuantification and identification of sulfated glycosaminoglycans in Lulo cells. After metabolic labeling of Lulo cells with 35 S-Na2SO4, cell extract, cell surface and cell culture medium were subjected to enzymatic degradation and afterwards to gel electrophoresis in 0.6% agarose. The bands were identified using an image analysis system, the Cyclone® Storage Phosphor System-Packard Instrument (A). Quantification was performed by densitometry with Opti-Quanti Software and expressed as cpm/mg protein (B). Defined quantities of non-labeled GAGs (chondroitin sulfate - CS; heparan sulfate - HS) were used as standard control; CTRL – incubation control with buffer; AC – chondroitinase AC; ABC – chondroitinase ABC; HEP II – heparinase II.Back to article page
