“…The buoyant density of the purified AF (fraction V) was determined to be 1.45 g/cm3. This value is in accordance with the chemical data, as given below, indicating a 1 :0.79 ratio between protein and total sugar components [5]. The ultraviolet spectrum (measured at pH 8.2 in CMF-SW) showed a maximum at 262 nm and a slight minimum at 244 nm.…”

“…Measurements of the diffusion coefficient were made with the rubber-valve-type synthetic-boundary cell according to the maximum ordinate-area method reported by Ehrenberg (1957) and outlined by Elias (1961). The solution of protein was prepared as described above and the solvent outside the dialysis sac was used as the upper phase.…”

Neurophysin has been separated into seven distinct protein fractions. One of these components had no hormone-binding activity. The fractions that had hormone-binding activity were similar in amino acid composition: their cystine content was in the range 11.5-14.5%. The major component, neurophysin-M, was distinguished from the protein isolated by van Dyke by the presence of methionine and the absence of histidine. Neurophysin-M binds both oxytocin and vasopressin with similar affinities.

Technetium / Extraction kinetics / Transfer coefficients / Ultracentrifuge / DiffusionSummary. The lack of published data on the extraction kinetics of Tc(VII) in the system U(VI)/HNO 3 //TBP/dodecane prompted us to investigate its transport behaviour in detail. The aim was to improve the U(VI)/Tc(VII) separation in the PUREX process. We choose the method of analytical ultracentrifugation to determine the concentration gradient profile, the initial flux density and the integral mass transport for both sides of the unstirred liquid-liquid interface as well as the overall mass transfer coefficients as a function of Tc(VII)-, U(VI)-concentrations and temperature from timedependent changes of the refractive index gradients. The results were supplemented by comparing the experimental with calculated concentration profiles, obtained by modeling a diffusion-limited extraction process. In some of the investigated systems, the transport at the interface is reaction-limited after phase contact. The determined values of J max , I, and α are discussed in terms of the extraction conditions.
