Core protein from bovine nasal proteoglycan has been obtained by cyanogen bromide cleavage and by removal of most of the glycosaminoglycan side chains by hydrogen fluoride treatment. Amino acid analysis of the cyanogen bromide fragment shows it to co

A cell that allows the structure of adsorbed protein layers to be examined by transmission circular dichroism is described. Sensitivity of the technique is demonstrated by presentation of spectra obtained from the adsorption of two blood proteins [bo

A new technique for studying the nature of adsorbed protein molecules based on fluorescence spectroscopy is described. The method was used for following the adsorption of bovine serum albumin (BSA) onto particulates. On random copolypeptide substrate

The adsorption and desorption of plasma proteins—albumin, γ-globulin, and fibrinogen—on copolypeptide and silicone surfaces have been studied. The process is characterized by three stages; an initial brief period where adsorption is reversible;

Hageman factor (factor XII) is activated by exposure to surfaces such as glass or by solutions of certain compounds, notably ellagic acid. Changes in the structure of Hageman factor accompanying activation have been examined in this study by circular

Kinetic and equilibrium studies of blood platelet binding to copolypeptide films show that attachment and serotonin release are not dependent upon the composition of the copolypeptide. Data may be explained by postulating that platelets frequently co

Spherulites of poly-L-proline II were grown by film casting from a dilute formic acid solution. Electron diffraction indicated that the molecular axis was parallel to the surface and essentially normal to the face of the lamellae. The molecular lengt
