NEW! Myeloperoxidase Activity Assays

In the presence of hydrogen peroxide, myeloperoxidase can exhibit two activities: chlorination and peroxidation, both of which can result in oxidative damage.

Our OxiSelect™ Myeloperoxidase Activity Assays provide a convenient method for measuring the chlorination or peroxidation activity levels of this enzyme.

NEW! s-Glutathione Adduct Competitive ELISA

Glutathione serves as an antioxidant and protects against oxidative damage, but it can also bond covalently with proteins via its sulfhydryl moiety in the presence of reactive oxygen species (ROS). Therefore, glutathione adducts can serve as a stable marker of oxidative stress in proteins.

Our OxiSelect™ s-Glutathione Adduct Competitive ELISA Kit provides a simple method for quantifying the levels of s-glutathionylation in proteins from a variety of sources including cells, lysates, plasma or serum.

NEW! Protein Radical ELISA

When free radicals come into contact with proteins, they can donate electrons to the proteins to form protein radicals. Protein radicals have been linked to various disorders including Alzheimer's Disease, Huntington's Disease, and amyotrophic lateral sclerosis.

Our OxiSelect™ Protein Radical ELISA Kit provides a unique way to measure these radicals using a technology known as spin trapping. Using this technology, a stable adduct is formed that can be quantified by standard ELISA.

NEW! Oxidized HDL ELISA Kits

High density lipoprotein (HDL) is often described as "good cholesterol" because of its protective properties against cardiovascular disease. However, when HDL becomes oxidized it can lose its cardioprotective benefits.

Our OxiSelect™ Oxidized HDL ELISA Kits provide a fast, convenient way to measure the oxidative damage to HDL in plasma or serum samples. The assays individually measure one of three prominent damage markers: malondialdehyde (MDA), 4-hydroxynonenal (HNE), and N-epsilon-(carboxymethyl) lysine (CML).
