Allgemeine Beschreibung

The new Ascorbic Acid Assay Kit, MAK505, is now available! Ascorbic Acid, also known as Vitamin C, is a six-carbon lactone produced by plants and some animal species but not by humans and other primates. Ascorbic acid functions as an enzymatic cofactor for multiple enzymes, serving as an electron donor for monooxygenases and dioxygenases. Ascorbic acid also functions as a powerful antioxidant, particularly in regards to reactive oxygen species.

Eignung

Suitable for use with biological fluids, food samples, and growth media. Proteins present in the sample can interfere with this assay. Protein containing samples are best analyzed using the Ascorbic Acid Assay II (MAK075). Alternatively, samples can be deproteinized using a 10 kDa Molecular Weight Cut-Off Spin Filter.

Prinzip

In this assay, Ascorbic Acid concentration is determined by a coupled enzyme reaction, which results in a colorimetric (570 nm)/fluorometric (λex = 535/ λem = 587 nm) product, proportional to the ascorbic acid present.
