Descrição geral

Peroxidase (POD) is an enzyme that includes a group of specific enzymes such as nicotinamide adenine dinucleotide (NAD) peroxidase, NADP peroxidase, fatty acid peroxidase and a group of non-specific enzymes from various sources. It is present in animals, higher plants and other organisms.

Aplicação

For direct conjugation to compounds containing free sulfhydryl groups for use as an enzyme-linked detection reagent.
Instructions for use included. In a study on horseradish peroxidase, the Maleimide compounds succinimidyl 4-maleimidobutyrate and succinimidyl 6-maleimidohexanoate have been shown to be the most effective in the conjugation of Fab′ to horseradish peroxidase. This enzyme has also been used in a study to investigate the effectiveness in staining a mitochondrial protein, lipoamide dehydrogenase.
To increase signal intensity of immunoconjugates, immunoglobulins were synthetically modified to contain multiple primary amines and covalently coupled to maleimide activated peroxidase. This can result in more efficient conjugation and signal amplification.

Ações bioquímicas/fisiológicas

Peroxidase (POD) helps in the dehydrogenation of several organic compounds like phenols, aromatic amines, hydroquinones etc.

Outras notas

Type VI peroxidase activated with maleimidocaproic acid N-hydroxysuccinimide ester.

Nine different maleimide compounds were evaluated for the conjugation of Fab' to horseradish peroxidase through thiol groups in the hinge. The compounds evaluated were succinimidyl maleimidoacetate (I), succinimidyl 4-maleimidobutyrate (II), succinimidyl 6-maleimidohexanoate (III), succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate (IV), succinimidyl m-maleimidobenzoate (V), succinimidyl
