A simple method for desalting biological fluids for paper chromatography of amino-acids.
A quick method of performing the Paul-Bunnell reaction is described which is as sensitive as the orthodox method. When read at two hours the rapid test appears to be definitely more sensitive than the orthodox method. When the rapid method is performed in the later stages of glandular fever a much higher titre is obtained than by the orthodox method. This might prove to be of diagnostic importa...

متن کاملSeparation of Amino Acids by Paper Chromatography
Chromatography is a common technique for separating chemical substances. The prefix “chroma,” which suggests “color,” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment, chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate...
متن کاملA Simple, Rapid Method for Paper Chromatography of Barbiturates.
Barbiturates are extracted quantitatively into ethyl ether from biologic fluids buffered to pH 6. A measured portion of the ether extract is then impinged to dryness and the residue spotted on Whatman No. 2 paper that has been previously dipped in alkali and dried. The paper is developed by descending chromatography with chloroform saturated with water. The barbiturate may then be located and a...
متن کاملAn Improved Method for Identification of Amino Acids in Descending Paper Chromatography
A change in paper shape is described for use in descending paper chromatography. The "flask-shaped" paper provides greater reliability in the identification of amino acids in unknown mixtures. As many as three samples of unknown and/or known components can be run simultaneously on the same paper and under the same conditions. The method has been used by other investigators for the separation of...
