A simple method for the determination of serum cholesterol

A new simple semimicro method for colorimetric determination of urea.

A simple colorimetric method for the determination of serum alpha-hydroxybutyric dehydrogenase activity.

An accurate, simple colorimetric method for the determination of serum alpha-hydroxybutyric dehydrogenase activity is described. The method is suitable for routine laboratory use.

Colorimetric method for the determination of lipoxygenase activity.

A colorimetic assay for lipoxygenase activity has been developed. The assay is based on the detection of the lipoxygenase reaction product, linoleic acid hydroperoxide, by the oxidative coupling of 3-methyl-2-benzothiazolinone (MBTH) with 3-(dimethylamino)benzoic acid (DMAB) in a hemoglobin-catalyzed reaction. This test reaction is rapid and sensitive, and it offers advantages over other method...

[Colorimetric method for the quantitative determination of plasma catalase activity].

HE STUDY OF CATALASE ACTIVITY has been the subject of much investigation and has necessitated the use of very elegant technics. Recently, methods have been introduced which simplified the technics for estimating catalase activity. Among these are the iodimetric titration procedure of Dille and Watkins (1), the use of sodium perborate as a source of hydrogen peroxide (2), and various methods uti...
