Binding of lectins to microbial cell walls was investigated by fluorimetric titration and Scatchard plot. Data were correlated with agglutinability. Concanavalin A and lectins of wheat germ, soybean, pea, lentil, and peanut were tested against Escherichia coli. Micrococcus luteus, Lactobacillus plantarum, and Bacillus subtilis. In cases where binding(More)
Tissue collagen exhibits several levels of structural organization, and this complicates efforts to determine the origin of its piezoelectricity. We made collagen films—by evaporation and electrodeposition from solution—and examined the relation between collagen's piezoelectricity and its electron microscopic appearance. We found that the electrodeposited(More)
Electric birefringence decay curves of collagen suspended in aqueous buffered media were plotted as functions of pulse width and amplitude. They were then resolved into two components by means of an analog simulator. When these data were combined with the results of repeated pulsing, it was shown that an electric field promotes aggregation of collagen,(More)
