Zhang, Yifei; Hess, Henry published an article on January 7 ,2020. The article was titled 《Inhibitors in Commercially Available 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonate) Affect Enzymatic Assays》, and you may find the article in Analytical Chemistry (Washington, DC, United States).Computed Properties of C18H24N6O6S4 The information in the text is summarized as follows:

ABTS, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate), is a common chromogenic substrate for peroxidase enzymes, which are widely used in biochem. research and diagnostic tests. We discovered that impurities in the com. available ABTS significantly affect the results of peroxidase activity assays. We show that the impurities inhibit the activity of the peroxidases and the influence varies for different batches of ABTS from the same source. The inhibition of horseradish peroxidase (HRP) is uncompetitive for the substrate H2O2 while it is competitive for the substrate ABTS. By using high-resolution mass spectrometry, potential inhibitors were identified to be precursors or analogs of ABTS. The inhibitors are also capable of inhibiting the GOx-catalyzed reduction of the ABTS radical cation by glucose in anaerobic conditions. As the inhibition is found to be pH-dependent, diagnostic applications, such as ELISA tests based on the peroxidase-H2O2-ABTS system, should be carried out at pH 4.4 to minimize the inhibitory effect of potentially present impurities.

Piechowiak, Tomasz; Skora, Bartosz; Sowa, Patrycja published their research in Journal of the Science of Food and Agriculture on February 28 ,2022. The article was titled 《Changes in the activity of flavanone 3β-hydroxylase in blueberry fruit during storage in ozone-enriched atmosphere》.HPLC of Formula: 30931-67-0 The article contains the following contents:

The present study aimed to determine whether the ozonation process affects the flavonoid biosynthesis in highbush blueberry (Vaccinum corymbosum L.) fruit. Flavanone 3β-hydroxylase (F3H) was used as a marker of the flavonoid biosynthesis pathway. The activity of F3H, the expression of gene encoding F3H and the antioxidant status in blueberries treated with ozone at a concentration of 15 ppm for 30 min, every 12 h of storage, and maintained at 4°C for 4 wk were investigated. The results showed that ozonation process increases the expression of the F3H gene after 1 wk of storage, which translates into a higher catalytic capacity of protein, as well as a higher content of flavonoids and total antioxidant potential of ozonated blueberries compared to non-ozonated fruits. The present study provides exptl. evidence indicating that ozone treatment in proposed process conditions pos. affects flavonoid metabolism in highbush blueberry fruit leading to the maintainance of the high quality of the fruit during storage.
