EnzyChrom Formate Assay Kit

Application

• Direct determination of formate concentrations in biological (e.g. urine, blood, etc.) and other samples.

Key Features

• Fast and sensitive. Use of 10 uL sample. Linear detection range 0.050 to 5 mM Formate in 96-well plate assay.
• Convenient. The procedure involves adding a single working reagent, and reading the absorbance after 60 minutes. Room temperature assay. No 37C heater is needed.

More Details

• FORMATE (HCOO^-) is the anion derived from formic acid, the simplest carboxylic acid. It is also the metabolic byproduct of formaldehyde metabolism in our body, and the eventual metabolic byproduct of methanol which is first broken down to formaldehyde. At high levels, formate is neurotoxic to the central nervous system and can cause blindness, coma, and death. Although naturally present in the body at low levels, elevated levels of formate may be used as an indicator of formaldehyde exposure and methanol poisoning. BioAssay Systems formate assay kit is based on formate dehydrogenase catalyzed oxidation of formate, which generates carbon dioxide and NADH that reduces a formazan (MTT) dye. The intensity of the reduced MTT, measured at 565 nm, is directly proportional to formate concentration in the sample.
