Datasheet:

ABTS method can be used to determine the antioxidant capacity of hydrophilic and lipophilic substances, and it is the

most widely used indirect detection method. ABTS is oxidized to form a stable blue-green cation ABTS radical with the

largest absorption peak at 405 nm or 734 nm. After the tested substance is added into ABTS free radical solution, the

antioxidant component can react with ABTS free radical to make the reaction system fade, and the absorbance of 405 nm

decreases. In a certain range, the change of absorbance is directly proportional to the degree of free radical removal. In this

kit, the sample's ability to scavenge ABTS radicals is reflected by measuring the degree of absorbance decrease.

Note: It is recommended to select 2-3 samples with large expected differences for pre experiment before test. If the

sample absorbance value is not within the measurement range, it is recommended to dilute or increase the sample size for

testing.

Reagents and Equipment Required but Not Provided

Constant temperature water bath, spectrophotometer, 1 mL glass cuvette, desktop centrifuge, mortar/grinder, drying box,

30~50 mesh sieve and distilled water.
