About 4-hydroxy-2-hexenal (4-HHE)

4-hydroxy-2-alkenal is one of the major lipid peroxidation products, and shows many biological effects such as high toxicity to cells. Among them, 4-hydroxy-2-hexenal (HHE) is an aldehyde formed during peroxidation of n-3 fatty acids such as docosahexaenoic acid. HHE is highly reactive aldehyde and reacts with histidine residue of protein to form Michael-addition type adducts. This antibody is specific for HHE-histidine Michael adduct (HHE-His) and enable to detect HHE-His in the tissue samples.

About Acrolein (ACR)

Acrolein (ACR) is a representative carcinogenic aldehyde found ubiquitously in the environment and formed endogenously through oxidation reactions, such as lipid peroxidation and myeloperoxidasecatalyzed amino acid oxidation. ACR is highly reactive aldehyde and reacts with lysine residue in protein. The reaction with ACR and lysine residue leads to the formation of numerous numbers of adducts, such as formyl-dehydropiperidino-lysine (FDP-lysine) type derivative. This antibody is specific for the ACR-modified protein, especially FDP-lysine type derivative.

About malondialdehyde (MDA)

Malondialdehyde (MDA) is one of the major aldehyde derive from lipid peroxidation. MDA is highly reactive aldehyde and reacts with lysine residue in protein. The reaction with MDA and lysine residue leads to the formation of numerous numbers of adducts, such as dihydropyridine-lysine (DHP-lysine) type derivative. This monoclonal antibody is specific for the MDA-modified protein, especially DHP-lysine type derivative.

About Dityrosine: A novel biomarker for protein oxidation

Tyrosine is one of the major targets of protein oxidation, and until today various tyrosine derivatives such as nitrotyrosine, dityrosine (DT) and halogenated tyrosine depending on the type of free radicals. DT is a tyrosine dimer derived from tyrosyl radicals which is formed by reactive oxygen species (ROS), metal-catalyzed oxidation, ultraviolet irradiation, and peroxidases. Dityrosine have been found in atherosclerotic lesions, and lipofuscin of pyramidal neurons of aged human brains. Dityrosine is one of the specific biomarkers for protein oxidation.

Anti­-Dibromo­-Tyrosine (DiBrY) monoclonal antibody 

février 24  |  Oxidative Stress, Products  |   admin

About Dibromo-Tyrosine

Neutrophils and eosinophils play an important role in the defence system against microbial infection. Myeloperoxidase (MPO) and eosinophil peroxidase (EPO) are known to catalyze formation of hypochlorous acid (HOCl) and hypobromous acid (HOBr). These reactive intermediates may react with proteins, lipids and nucleotides, and it has been reported to form tyrosine halogenation such as dibromotyrosine (DiBrY). DiBrY is a Br-modified tyrosine at 3- and 5- position, which is one of the major oxidative products derived from neutrophil myeloperoxidase.

Anti-Tymidine Glycol (TG) Monoclonal Antibody

février 24  |  Oxidative Stress, Products  |   admin

About Thymidineglycol: A DNA oxidation marker

Thymidineglycol (TG) is one of the major oxidation products of DNA. Thymidine (T) can be damaged by oxidative stress such as radiation and energy metabolism. Two different pathways to form TG have been suggested. Deoxythymidine in DNA is directly oxidised by hydroxy radical, to form TG. TG can be also formed through an intermediate thymidine chlorohydrin, which is derived from hypochlorous acid (HOCl) from neutrophil myeloperoxidase. Thymidineglycol is derived from DNA, not from RNA. TG is the oxidative stress marker secific for DNA damage.
