✦ Synopsis

Methods of qualitative analysis of organic base polythionates are described. Paper electrophoresis in the 0.05 M triethylammonium bicarbonate buffer with a pH of 7.5 permits the analysis of polythionates of organic and inorganic bases. In this case, large amounts of colloidal sulphur and halogens do not interfere with the determination of higher polythionic acids. However, we failed to separate decylquinolinium tetrathionate by electrophoresis.

Thin-layer chromatography on a layer of Kieselgel G + IO y. of Dowex 50 W-X8 in the K+ form + 2% of potassium acetate makes it possible to analyse any polythionates, independent of the solubility and structure of the initial base, and the results of the separation of organic and inorganic polythionates agree well.

Two novel assay systems for the determination of sialyltransferase activity using a tetramethylrhodamine-labeled disaccharide Gal␀1-4GlcNAc (2) as the acceptor are described. The TMR-labeled disaccharide 2 was synthesized by directly coupling Gal␀1-4GlcNAc-O-(CH 2 ) 6 NH 2 (1) with 5-tetramethylrhod

Base ratio analysis of small amounts of RNA isolated from human specimens requires a sensitive and reproducible method at the level of 5-10 pg of hydrolyzates. We have found that a modification of the method described by Smith and Markham (1) meets both these requirements. Complete separation in 2.
