Description_x000D_ General description_x000D_ Aldehydes are highly reactive molecules, which play a role in many physiological, pathological and commercial processes. They have been implicated as environmental pollutants, and in neurodegeneration and DNA damage. A method for rapid and accurate measurement of aldehydes is an important tool for biological and chemical research, the food industry, and environmental pollution surveillance._x000D_ Suitability_x000D_ This kit is suitable for the detection of aldehydes in a variety of samples, particularly when the samples are at a lower pH. When working with samples in a high pH, product number MAK139, Colorimetric Aldehyde Assay, is more suitable._x000D_ Principle_x000D_ The Colorimetric Aldehyde Assay Kit, Blue provides a simple and direct procedure for measuring aldehydes in a variety of samples. Aldehydes reacts with a sensor, resulting in a colorimetric (620 nm) product proportional to the amount of aldehyde present. The Colorimetric Aldehyde Assay Kit, Blue has a lower limit of detection of 0.3 nanomole of aldehyde in a 100 μL assay volume (3 μM).
