Despite the availability of various alkaline phosphatase (ALP) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. The glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (WGA). As a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...

The enterotoxins (ETs) of Clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. The ETs from alpaca, pig, and calf isolates were chromatographed on Sephadex G-lOO. Monoclonal antibodies (MAbs) against ETs derived from alpaca, pig, and calf C. perfringens isolates were produced. The MAbs were used...

Antibacterial properties of TiO2, ZnO as well as mixed TiO2-ZnO nanoparticles coated low density polyethylene films on Staphylococcus aureus PTCC1112 were investigated. Bactericidal efficiency of 0.5, 1 and 2 Wt% for TiO2 and ZnO nanoparticles and also 1 Wt% mixed TiO2-ZnO nanoparticles with TiO2:ZnO ratios of 25:75, 50:50 and 75:25 were tested under UV and fluorescent lights exposure at two di...
