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

The theoretical conformations of poly (Gly-Ala-Glu) have been studied. This peptide was chosen as a model for the glycine led triads of the polar regions in collagen. The most favorable conformations are found to be based on the extended and folded f

Single crystals of POAHP II were grown from acetic anhydride, a solvent in which POAHP I is thought to be stable. The single crystals gave an electron diffraction pattern which specified a hexagonal unit cell and the lateral spacing between molecular

Epitaxial deposition of homopolymers from solution [polyethylene, isotactic polystyrene, poly-3,3-bischloromethyloxacyclobutane (Penton) and polypropylene] was found on the (001) faces of cleaved alkali halide single crystals. Electron and optical mi

The nucleation of droplets of polyethylene, polyethylene oxide, polyoxymethylene, nylon 6, poly (3,3‐bis‐chloromethyloxacyclobutane), isotactic polypropylene, and isotactic polystyrene, suspended in silicone oil, has been investigated. Under cond
