The detection limit of the assay was less than 1ng per sample. The method proposed can be used for quantitative DAAO determination in the range of 0.13 to 3.60ng enzyme per probe. The protocol was successfully tested to screen a library of E. coli clones containing mutant DAAOs active toward target substrates. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
