We are happy to belatedly announce the release of our new Ferric Reduction Antioxidant Potential (FRAP) Assay Kit (DFRAP-100)!

FERRIC REDUCTION ANTIOXIDANT POTENTIAL (FRAP) is a measure of antioxidant capacity quantified by the antioxidant?s potential to reduce ferric iron (III) to ferrous iron (II). Antioxidants protect cells from damage by reactive oxygen species that are produced by oxidation reactions. As oxidative stress contributes to the development of many diseases including Alzheimer's disease, Parkinson's disease, diabetes, rheumatoid arthritis and neurodegeneration, the use of antioxidants in pharmacology is intensively studied. Antioxidants are also widely used as dietary supplements and as preservatives in a wide range of products such as food, cosmetics, rubber and gasoline.

Simple, direct and high-throughput assays for antioxidant capacity find wide applications in research, food industry and drug discovery. BioAssay Systems' improved assay measures antioxidant potential in which Fe3+ is reduced by antioxidant to Fe2+. The resulting Fe2+ specifically forms a colored complex with a chromogen. The color intensity at 590 nm is proportional to FRAP in the sample.

We are happy to announce the release of our new L-Amino Acid Assay Kit! (ELAA-100)

L-AMINO-ACIDS are the building blocks of proteins in biology. Almost all of the common 20 amino acids exist as the L-enantiomer.
BioAssay Systems' L-amino acid assay uses an enzyme-catalyzed oxidation of Lamino acids to convert a dye into a colored and fluorescent form. The absorbance at 570 nm or fluorescence intensity at λex/em = 530/585 nm is directly proportional to the L-amino acid concentration in the sample.

We are happy to announce the release of our new Oxalate Quick Test Strips!

OXALATE, or Oxalic Acid, is a metabolic breakdown product of the Kreb's Cycle in eukaryotes and the glyoxylate cycle in other microorganisms. Typically present in the urine of humans and other mammals, oxalate concentration can be used as a measure of kidney function. A high level of oxalate is an indicator for kidney stones, which are primarily made of the insoluble salt calcium oxalate. Measuring oxalate is more accurate than measuring calcium as a marker for kidney stones because calcium is excreted at high concentrations even in normal urine.

BioAssay Systems' QuantiQuik™ Oxalate Quick Test Strips are based on the enzymatic oxidation of oxalate coupled with a color reaction in one step. The intensity of product color is directly proportional to the oxalate concentration in the sample.
