NWLSS™ Total Antioxidant Capacity against Peroxyl Radical (TAC-Peroxyl) Assay
The NWLSS™ TAC-Peroxyl Antioxidant Capacity kit is intended for the quantitative measurement of a sample's antioxidant status against peroxyl radical challenge. This product represents a more concise tool allowing investigators to assess a sample's antioxidant capacity against a specific, biologically relevant free radical species. The peroxyl radical is involved in lipid peroxidation and other biologically significant pathways. This product is useful for testing many types of samples including blood plasma or serum, CSF, tissue homogenates, cell lysates, seminal plasma, wine, fruit juices, brewed teas and other botanical extracts. Data generated is in Trolox equivalents similar to the popular ORAC assay.

Catalog: NWK-ARC01
NWLSS™ Antioxidant Reductive Capacity (Antioxidant Status) Assay
The NWLSS™ Antioxidant Capacity kit measuring a sample's ability to reduce Cu++ to Cu+ as a means of assessing antioxidant status. The kit is useful as a simple method to quantify generic antioxidant capacity in many types of aqueous samples including serum, plasma, cell culture media and food extracts.
