A rapid electrophoretic method for the separation of hydroxyproline from proline

Summary A rapid, sensitive procedure is described which uses custom made apparatus to separate radioactive imino acids. This technique provides a simple measurement of the distribution of newly synthesized collagen in different fractions.Acknowledgment. This work was supported by grants from the International Wool Secretariat.     

Simple apparatus for perfusion fixation for electron microscopy.

Control on duration of application and pressure of fixative is achieved with an apparatus of simple construction. This allows optimal fixation of laboratory animals for morphological and cytochemical studies.     

A method for the separation and estimation of catechol amines in urine

Zusammenfassung Es wird eine neue Methode zur Bestimmung der Katecholamine im Harn beschrieben. Die Katecholamine werden im Harn acetyliert und die Acetylderivate papierchromatographisch im Bush-?C?-System getrennt. Nach erfolgter Trennung werden die einzelnen Katecholamine mit ?thylendiamin kondensiert und fluorimetrisch untersucht. Eine Spezifit?tserh?hung der Methode durch Anwendung doppelt markierter Isotopen wird in Betracht gezogen.      

A rapid micro radial electrophoretic method of protein separation on cellulose acetate membranes.

A new rapid micromethod for protein separation under a radial electric field is described. As many as 12 rabbit serum samples could be separated in 4--6 min.     

A simple method for separation and determination of aldosterone,hydrocortisone and corticosterone

Zusammenfassung Eine Mischung von Corticosteroiden (Corticosteron, Cortison, Hydrocortison und Aldosteron) und Oestrogenen (Oestron, Oestradiol und Oestriol) wurde mit Hilfe der Dünnschichtchromatographie getrennt. Die quantitative Bestimmung von Aldosteron geschah mit Hilfe der Fluoreszenz in konzentrierter Schwefelsäure.     

Simple theoretical criterion of chemical carcinogenicity - a refutation.

The quasi-valence number criterion for chemical carcinogenicity has been shown, through several examples, to be untenable.     

Simple,geometrical model for a typical echinocyte III

Summary The purpose of the present work is to obtain information relative to the volume and surface area of echinocyte, type III, on the basis of simple, micrographical evidence. A concrete case has been examined as direct demonstration of theory and techniques of calculus.     

A rapid micro radial electrophoretic method of protein separation on cellulose acetate membranes

Summary A new rapid micromethod for protein separation under a radial electric field is described. As many as 12 rabbit serum samples could be separated in 4–6 min.The authors are thankful to Dr P.K. Ramachandran, Defence Research and Development Establishment, Gwalior, for the sustained interest and helpful suggestions.
