An electrochemical method is described for the sensitive detection of the activity of the enzyme T4 polynucleotide kinase (PNK) by using a DNA functionalized porphyrinic metal-organic framework (L/(Fe-P)n-MOF). In the presence of PNK, the hairpin oligonucleotide (HP1) becomes phosphorylated, and the trigger is released by lambda exonuclease (λ exo). The trigger DNA hybridizes with hairpin probe (immobilized...
The most common methods for determination of uric acid in serum are based on the use of the enzyme uricase. Uric acid is enzymatically oxidized by oxygen to produce hydrogen peroxide, allantoin, and carbon dioxide. The four most often applied uricase methods are critically compared in this review.
