Partial purification and determination of molecular weights of glyoxalases by filtration on dextran gel.

Glyoxalase I and glyoxalase II (EC. 4.4.1.5 and EC 3.1.2.6) were separated by gel filtration on Sephadex G-75 and G-100. This simple procedure permitted also the partial purification of glyoxalase II. The purification coefficient in a single run from supernatant from beef liver was about 1 : 30 compared with 1 : 15 after the fifth step of purification with classical methods.

Determination of allantoin in biological, cosmetic, and pharmaceutical samples.

Methods for determining allantoin in biological, cosmetic, and pharmaceutical samples are reviewed. The methods cover 3 main categories: spectrophotometry, alkalimetric titration, and chromatography (thin-layer and liquid). Comments are given on suitability for different sample types and on further development of methods for allantoin determination.
