The effect of surface adsorption on the structure and stability of proteins is a matter of increasing interest in biotechnology. Therefore, we have examined the effect of adsorption to silica on the thermal stability of 7 proteins employing different

Cryoimmunoglobulins are associated with numerous clinical problems ranging from collagen vascular disorders (rheumatoid arthritis and systemic lupus erythematosus) to infectious processes including HIV infection. The precise role of cryoglobulins in

The interaction of three monoclonal rheumatoid factor IgM molecules with IgG antigens has been studied utilizing immunoglobulins isolated from three mixed cryoglobulins. Static light scattering measurements show that the stoichiometry of these immune

Differential scanning calorimetry was performed on the five major lens crystallin fractions [HM-alpha, alpha, beta H, beta L, and (beta s + gamma)] of the bovine lens as well as on more purified forms of alpha- and gamma-crystallins. All were found t

The kinetics of the cryoprecipitation of two monoclonal IgG and two monoclonal IgM cryoimmunoglobulins, two IgM/IgG mixed cryoglobulins and a series of cold soluble monoclonal IgG and IgM immunoglobulins in the presence of polyethylene glycol have be

The direct calorimetric determination of heats of solution for four monoclonal and three mixed (IgM/IgG) cryoglobulins is described. Values obtained by differential scanning calorimetry (DSC) are compared to values of the apparent delta Hsol obtained

Inhibition of the cryoprecipitation of cryoimmunoglobulins by neutral salts suggests that intermolecular electrostatic (charge-charge) interactions are responsible for their abnormal solution properties. To test this hypothesis, H+ titration curves a

A major problem encountered with the use of electronic spectroscopy in the analysis of biological materials in the ultraviolet, visible, and infrared region involves the limited range of the physical state of samples that can be examined. In an attem

The compound N-cyclohexyl-2-pyrrolidone contains a substantial apolar region as well as a peptide bond-like moiety. This solvent, therefore, provides a useful model for protein interiors. Under certain conditions of temperature and salt concentration

The thermodynamics of both normal and abnormal (disease-associated) protein solubility has been examined. It is shown that the atypical behavior of monoclonal cryoimmunoglobulins can be explained by the formation of one or a few additional electrosta
