Comments on Gene-Enzyme Relationship’

formulations of genetics leave us less and less tangible knowledge of how the genes work. We can only hope that genetics has asked the right questions, which are now ready for the frontal attacks of biochemistry. 1. Allison, A. C., Science 122, 640. (1955). 2. Beadle, G. W., in “Genetics in the 20th Century” (L. C. Dunn, ed.). The

Automation of enzyme assays.

The increasing use of enzymes as aids to clinical diagnosis has made it mandatory for clinical biochemists to develop techniques and instrumentation to enable large numbers of specimens to be processed quickly with adequate accuracy. The main objective in enzyme assay is to determine the initial reaction rate, as it is only during this period that there is a linear relationship between the rate...

Enzyme assays in liver disease.

It is in the field of hepatology that enzyme assays are performed most frequently for diagnostic purposes. Their interpretation requires knowledge of many factors that influence the serum level of the particular enzymes assayed. Therefore, these factors are discussed briefly in relation to liver disease before considering important developments such as the value of estimating D-glutamyltransfer...
