widely used antioxidant assay kit in vietnam
Antioxidant Assay Kit sufficient for 100 colorimetric or
Simple, direct and high-throughput assays for total antioxidant capacity (TAC) find wide applications in research, food industry and drug discovery. The Antioxidant Assay Kit’s improved assay measures total antioxidant capacity in which Cu 2+ is reduced by antioxidant to Cu +. The resulting Cu + specifically forms a colored complex with a dye reagent. The color intensity at 570nm is proportional to TAC in the sample.

DPPH Assay - an overview | ScienceDirect Topics
2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay is the most commonly used antioxidant assay for plant extract. In this assay, a molecule or antioxidant with weak A-H bonding will react with a stable free radical DPPH• (2,2-diphenyl-1-picrylhydrazyl, λmax=517 nm) causing discoloration of the molecule.

K515 Ferric Reducing Antioxidant Power Assay Kit
Ferric reducing antioxidant power (FRAP) assay is a widely used method that uses antioxidants as reductants in a redox-linked colorimetric reaction, wherein Fe3+ 3+is reduced to Fe2+. Ferric (Fe ) to ferrous (Fe2+)ion reduction at low pH causes formation of a colored ferrous-probe complex from a colorless ferric-probe complex.

Antioxidant Activity/Capacity Measurement. 1
a reliable antioxidant protocol requires the measurement of more than one property relevant to either foods or biological systems.5 (v) A noteworthy question is that, if the protective action of an antioxidant is being assayed in a selected test, what biomolecule (lipid, protein, DNA, etc.) is the antioxidant supposed to protect and how?
Send InquiryA Comparative Study on the Antioxidant Activity
The Oxygen Radical Absorbance Capacity (ORAC) assay determined the antioxidant potential of the extracts, while the ROS scavenging ability was explored in hyperglycemia-induced human umbilical vein endothelial cells (HUVECs). The SOD assay determined if the extracts stimulated the enzyme activity in the HUVECs.

Antioxidant Activity by DPPH Assay of Potential Solutions
dPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free radical method is an antioxidant assay based on electron-transferthat produces a violet solution in ethanol (10). This free radical, stable at room temperature, is reduced in the presence of an antioxidant molecule, giving rise to colorless ethanol solution.
