Herein, we describe a modified ELISA method used to evaluate the interaction of a recombinant Schistosoma mansoni protein with plasminogen (PLG). Using this protocol, we demonstrated that a secreted protein, recombinant venom allergen-like protein 18 (rSmVAL18) acts as a plasminogen receptor increasing its activation into plasmin in the presence of the urokinase-type plasminogen activator (uPA). PLG binding was determined by immobilizing human PLG in the plate and incubating with the recombinant protein; competitive binding with a lysine analog demonstrated the interaction of the protein lysine residues with PLG Kringle domains. To assess the activation of S. mansoni recombinant protein-bound PLG, the amidolytic activity of generated plasmin was measured using the D-Val-Leu-Lys 4-nitroanilide dihydrochloride substrate.Electrophysiology is the standard method for characterizing ion channel function. Two-electrode voltage clamp is a robust and relatively simple version which can be applied to the characterization of glutamate-gated chloride channels from Schistosoma mansoni, a potential schistomicidal target. Here, the method is described in detail, with an emphasis on the investigation of S. mansoni. GluCls.Dihydrofolate reductase (DHFR) is an essential enzyme for nucleotide metabolism used to obtain energy and structural nucleic acids. Schistosoma mansoni has all the pathways for pyrimidine biosynthesis, which include the thymidylate cycle and, consequentially, the DHFR enzyme. Here, we describe the characterization of Schistosoma mansoni DHFR (SmDHFR) using isothermal titration calorimetry for the enzymatic activity and thermod
