Exposure to polycyclic aromatic hydrocarbons has often been quantified via DNA or human serum albumin (HSA) adducts of the carcinogenic metabolite benzo[a]pyrene diol epoxide (BPDE). We previously reported a sandwich ELISA, using 8E11 as capture antibody and anti-HSA as detection antibody, that dete

BACKGROUND: The Kato-Katz technique is widely used for the diagnosis of Schistosoma mansoni, but shows low sensitivity in light-intensity infections. We assessed the accuracy of a commercially available point-of-care circulating cathodic antigen (POC-CCA) cassette test for the diagnosis of S. manson

Protein digestion is an integral part of the "shotgun" proteomics approach and commonly requires overnight incubation prior to mass spectrometry analysis. Quadruplicate "shotgun" proteomic analysis of whole yeast lysate demonstrated that Guanidine-Hydrochloride (Gnd-HCl) protein digestion can be opt

BACKGROUND: Parasitological methods are widely used for the diagnosis of schistosomiasis. However, they are insensitive, particularly in areas of low endemicity, and labour-intensive. Immunoassays based on detection of anti-schistosome antibodies have the merit of high sensitivity and recently a rap
