Analysis of protein carbonyls in meat products by using the DNPH-method, fluorescence spectroscopy and liquid chromatography–electrospray ionisation–mass spectrometry (LC–ESI–MS)

Jian carp ( Cyprinus carpio var. Jian) intestinal immune responses, antioxidant status and tight junction protein mRNA expression are modulated via Nrf2 and PKC in response to dietary arginine deficiency

“…Malondialdehyde (MDA) was measured using the method of Livingstone, Martinez [32]. Protein carbonyl (PC) was determined according to the method described by Armenteros, Heinonen [33], with a minor modification. The superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities were measured using the method of Lu, Wang [34] and Zhang, Zhu [35], respectively.…”

Changes in barrier health status of the gill for grass carp (Ctenopharyngodon idella) during valine deficiency: Regulation of tight junction protein transcript, antioxidant status and apoptosis-related gene expression

“…Protein carbonyl (PC) content residue content was measured as described by Armenteros et al [45]. Malondialdehyde (MDA) was assayed using the thiobarbituric acid reaction as described by Zhang et al [46].…”

Effect of dietary isoleucine on the immunity, antioxidant status, tight junctions and microflora in the intestine of juvenile Jian carp (Cyprinus carpio var. Jian)

“…Lipid and protein peroxidation levels were determined based on malondialdehyde (MDA) and protein carbonyl content, which was measured according to Zhang et al [53] and Armenteros et al [54], respectively. The protein concentration of samples was determined by the method of Bradford [55] using the Coomassie Brilliant Blue dye binding technique with bovine serum albumin as the standard.…”
