The condensing peptide forming multienzyme of gramicidin S synthetase (gramicidin S synthetase 2) was specifically labeled at its putative thiotemplate sites for L-valine and L-leucine by covalent incorporation of the 14C-labeled substrate amino acids. The thioester complexes of the multienzyme were digested with CNBr, Staphylococcus aureus V8 protease, and pepsin. Reaction center peptides cont...
Serum concentrations of cancer antigen (CA) 19-9 can be useful in monitoring response to therapy in pancreatic cancer. The objective of this study was to evaluate 5 automated CA 19-9 assays: ARCHITECT 12000 (Abbott Diagnostics, Abbott Park, IL), ADVIA Centaur (Bayer Diagnostics, Tarrytown, NY), UniCel Dxl 800 (Beckman Coulter, Fullerton, CA), IMMULITE 2000 (Diagnostic Products, Los Angeles, CA)...
