A new enzymatic assay for specifically measuring allantoin concentration in serum has been developed. The currently used methods for allantoin analysis are time consuming and nonspecific or depend on the use of expensive equipment. In our method, allantoin is converted to allantoate by the action of allantoinase (EC 3.5.2.5). The allantoate produced is(More)
Current conventional measurement of allantoin levels in human serum uses an HPLC method. However, performing this assay is time-consuming and sample-intensive, and it requires expensive equipment. We have developed a novel enzyme cycling method for measuring allantoin concentrations in human serum. In the first step, serum allantoin is converted to(More)
Analysis of serum proteins by native polyacrylamide gel electrophoresis is difficult because albumin is abundant in serum and interferes with the resolution of other proteins, especially alpha-antitrypsin which has mobility that is very similar to that of albumin. We present here a method in which serum proteins are separated by polyacrylamide gel(More)
