More Details

FORMALDEHYDE (methanal) is the simplest aldehyde. It is widely employed in industry for a wide range of applications. Formaldehyde is also used as a disinfectant and is a commonly utilized tissue fixative and embalming agent. Formaldehyde is naturally present in all tissues and body fluids. Recently, it has been shown that some cancer types exhibit elevated formaldehyde levels. Increased formaldehyde concentration in urine has been associated with prostate and bladder cancer. Thus, measuring formaldehyde in urine can be a very useful tool when studying cancer.BioAssay Systems’ formaldehyde assay kit is based on formaldehyde dehydrogenase catalyzed oxidation of formaldehyde, which generates formate and NADH that reduces a formazan (MTT) dye. The intensity of the reduced MTT, measured at 565 nm, is directly proportional to formaldehyde concentration in the sample.

What additional materials are required, but not provided?

Pipetting devices, centrifuge tubes, clear flat-bottom 96-well plates (e.g. VWR cat# 82050-760), and plate reader.

What is the conversion for μM to ppb for formaldehyde?

1 μM equals 30 ppb formaldehyde.
