A new fluorescence in situ hybridization (FISH) method using peptide nucleic acid (PNA) probes and an array scanner for rapid detection, identification, and enumeration of Escherichia coli is described. The test utilizes Cy3-labeled peptide nucleic acid (PNA) probes complementary to a specific 16S rRNA sequence of E. coli. Samples were filtered and(More)
High-resolution proton nuclear magnetic resonance spectra of low- and high-density lipoproteins from human serum closely resemble those of dispersions of lipoprotein lipids in water. Linewidths of hydrocarbon proton absorptions are not increased in the lipoproteins. In contrast, apolar binding of lysolecithin on serum albumin causes extensive(More)
