Thiopental binding to serum albumin

Zusammenfassung Die Bindungskapazität und die Anlagerungskonstante von Thiopental an Rinderalbumin wurde bei pH 7,42 in Trispuffer bei einer Temperatur von 7°C nach der Methode der Gleichgewichtsdialyse gemessen. Die Bindungskapazität betrug 5 und die Vergleichskonstante war 12000. Durch Zugabe von EDTA wurde die Bindungskapazität auf 4 reduziert; gleichzeitig verringerte sich die Anlagerungskonstante auf 10000.     

The chemokinetic effect of serum albumin

Summary Experiments performed by means of time lapse cinematography or the filter technique show that human serum albumin has marked chemokinetic effects on neutrophil cultured in Gey's solution. The average speed of the cells, as well as the proportion of neutrophils showing locomotion, is increased. Enhanced locomotion correlates with decreased attachment to the substratum as determined by morphological and functional criteria.We thank Mrs R. Graf and Miss M. Schuster for technical assistance.

The influence of albumin on the electrophoretic mobility of serum lipids

Zusammenfassung Im Gegensatz zuMaurers Angaben konnte keine Wirkung des dem Puffer zugegebenen Serum-Albumins auf die elektrophoretische Wanderung von Serumphospholipiden und Cholesterin im menschlichen und tierischen Serum festgestellt werden.Maurers Befunde scheinen auf einer durch Adsorptionseffekte bewirkten Veränderung der Lipoproteine zu beruhen.

Polarographic catalytic waves of ultraviolet irradiated and urea denatured bovine serum albumin

Zusammenfassung Serumalbumin von Rindern wurde in 2 verschiedenen Konzentrationen mit UV-Licht bestrahlt und die polarographisch-katalytischen Wellen mit denen von Albumin verglichen, das zuvor mit Harnstoff behandelt worden war.

Long-term persistence of bovine serum albumin when injected into the amphibianXenopus laevis Daudin

Résumé Dans ces expériences leXenopus laevis, maintenu à 23°C, n'a pas formé d'anticorps en présence de l'albumine du sérum bovin (BSA). La BSA se conserve plusieurs mois dans le sérum de tous les animaux expérimentaux.     

On the origin of the antiheparin activity of serum. The effect of reserpin

Zusammenfassung Es wurde gezeigt, dass Zusatz von Reserpin zum Blut die Antiheparinaktivität im Serum deutlich steigert. Da Reserpin zugleich die Thrombocyten beeinflusst, wird vermutet, dass diese für die Antiheparinaktivität verantwortlich sind.     

Inhibitory effectin vitro of some polysaccharides and of horse serum albumin on mitochondrial swelling

Riassunto Si è studiato l'eventuale effetto protettivo, esercitato da alcuni polisaccaridi: il glicogeno di fegato, la pectina di mele, la gomma arabica, e dell'albumina del siero di cavallo su mitocondri di fegato di ratto sospesi in soluzione isotonica di saccarosio. Si è osservato come le suddette sostanze esercitino un effetto inibitore sopra il rigonfiamento spontaneo mitocondriale.     

Transfer and induction of delayed hypersensitivity to methylated bovine serum albumin in the absence of adjuvant]

Delayed hypersensitivity to methylated bovine serum albumin may be induced in Mice without adjuvant, by injecting the antigen either with sensitized T lymphocytes, or by injecting just the antigen in Mice preptreated with Cyclophosphamid.     

Effect of volatile anesthetics on the circular dichroism of bilirubin bound to human serum albumin

The characteristic circular dichroism of bilirubin bound to human serum albumin undergoes a remarkable sign inversion on addition of halothane, chloroform and other volatile anesthetics. This sign inversion, which is completely reversed by removal of the anesthetic, reflects a pronounced conformational change of the bound ligand; probably a complete inversion of chirality. The observation suggests that association of volatile anesthetics with proteins can markedly alter the internal topography of receptor sites and potentially influence the stereoselectivity of ligand binding.
