[Less] The interfacial tension gamma of hexane solution of 1,1,2,2-tetrahydroheptadecafluorodecanol (FC10OH) . . . [More] The interfacial tension gamma of hexane solution of 1,1,2,2-tetrahydroheptadecafluorodecanol (FC10OH) against water was measured as a function of pressure p and molality m(1) at 298.15 K. The break points were observed on the gamma vs p and gamma vs m(1) curves. The interfacial density Gamma(1)(H) increases and the volume change associated with the adsorption Delta nu decreases with increasing m(1), and they change discontinuously at concentrations of the break points. By drawing the interfacial pressure pi vs area A curve, it is concluded that two types of phase transitions take place from the gaseous to the expanded state and from the expanded to the condensed one in the adsorbed film of FC10OH. By examining our results by the Clapeyron type equations, the order of phase transition was considered first. The partial molar volume change associated with the adsorption of FC10OH was estimated and compared with that of 1-octadecanol (C18OH) It was found that FC10OH molecules were accompanied with the larger decrease in partial molar volume inherent in the interface than C18OH molecules when the phase transition takes place from the expanded to the condensed state in the adsorbed film. This suggests that the microscopic circumstance in the adsorbed film affects appreciably the volume change of adsorption.

Thermodynamic study on phase transition in adsorbed film of fluoroalkanol at the hexane/water interface .2. Pressure effect on the adsorption of 1,1,2,2-tetrahydrohenicosafluorododecanol

[Less] The adsorption behavior of 1,1,2,2-tetrahydrohenicosafluorododecanol, CF3(CF2)(9)(CH2)(2)OH(FC12OH), . . . [More] The adsorption behavior of 1,1,2,2-tetrahydrohenicosafluorododecanol, CF3(CF2)(9)(CH2)(2)OH(FC12OH), at the hexane/water interface was investigated in both the absence and presence of the deposit by measuring the interfacial tension gamma of its hexane solution against water as a function of pressure p and molality m(1) at 298.15 K. It was concluded that a breakpoint on the gamma vs p and gamma vs m(1) curves in a very low concentration region shows a first-order phase transition from the gaseous to the condensed state in the adsorbed film. It was found that the volume change of adsorption per mole of FC12OH is larger than that of 1,1,2,2-tetrahydroheptadecafluorodecanol, CF3(CF2)(7)(CH2)(2)OH(FC10OH). Then it was suggested that the increase in the partial molar volume of alcohol with increasing fluorocarbon chain length is larger in the solution than in the interface because of the weak mutual interaction of the fluorocarbon chain with hexane molecules. Furthermore, another breakpoint due to the solubility of FC12OH in hexane was observed on the gamma vs p and gamma vs m(1) curves in a high concentration and pressure region. A small value of partial molar volume change accompanied by the adsorption from the solid substantiates our view that the condensed state of the adsorbed film resembles the solid state.

PARAFORMALDEHYDE FIXATION OF NEUTROPHILS FOR IMMUNOLABELING OF GRANULE ANTIGENS IN CRYOULTRASECTIONS

[More] Paraformaldehyde (PFA) fixation was optimized to facilitate the immobilization and labeling of multiple granule antigens, using short fixation regimens and cryoultramicrotomy of unembedded neutrophils (PMNs). In the optimal protocol, extraction of azurophil granule antigens (especially of the abundant elastase) was obviated by manipulating the polymeric state of PFA, and hence its rate of cross-linking, by altering its concentration and pH in a multistep process, Primary fixation conditions used (4% PFA, pH 8.0, 5 min) favor fixative penetration and rapid cross-linking, Stable crosslinking of the antigen was achieved in a secondary fixation step using conditions that favor larger, more cross-linking polymeric forms of PFA (8% PFA, pH 7.2, 15 min), Immobilization of granule antigens was enhanced by flotation of cut sections on fixative (8% PFA, pH 8.0) before labeling and by using post-labeling fixation with 1% glutaraldehyde. The optimized protocol facilitated immobilization and immunolabeling of elastase, myeloperoxidase, lactoferrin, and cathepsin D in highly hydrated, unembedded PMNs.
