How specific is this assay for acetaldehyde?
The assay mechanism uses the enzyme aldehyde dehydrogenase to quantify acetaldehyde in the sample. The enzyme will also oxidize other aldehydes in the sample (i.e. propionaldehyde). Therefore, the assay will not distinguish between acetaldehyde and other aldehydes present in the sample. Consideration should be taken if high levels of other aldehydes are expected in the sample being tested.How long are the diluted standards good for?
Acetaldehyde is a rather volatile chemical, so proper storage of the standard is vital. Only bring the 3 M Standard to room temperature for time needed to prepare standards. Return to -20°C within 30 minutes of thawing. Be sure to keep the Standard and standard dilutions on ice or refrigerated with the tube caps closed during assay procedure. The diluted standards for the colorimetric assay (4 mM, 2.4 mM, 1.2 mM, and 0 mM) and the fluorimetric assay (60 µM, 36 µM, 18 µM, and 0 µM) should be prepared fresh before each assay and used within 10 minutes of preparing.What temperature do I run the assay at?
The assay may be run at room temperature (25°C) or 37°C.For more detailed product information and questions, please feel free to Contact Us. Or for more general information regarding our assays, please refer to our General Questions.
