Description
PAC Assay Kit Principle
Bioquochem’s Proanthocyanidins PAC Assay Kit consist on the reaction of 4-dimethylaminocinnamaldehyde (DMAC) with procyanidins’ A cycle’s C8, in terminal units of proanthocyanidin. This reaction produces a green/blue colored compound that the user can measure by spectrophotometry at 640 nm. As a result, this wavelength excludes the spectra of anthocyanidins, which are a source of interference in other assays. PAC Assay Kit is an accurate, reproducible and rapid method.
Information
PACs are polymeric condensation products, responsible for many bitter and astringent flavors in food products such as wine, chocolate, beer, and cranberries. They are widely distributed in nature and represent the most abundant flavonoids consumed in the diet. Hence, these comopunds are of special interest nowadays. That is because of their health-promoting properties toward chronic diseases and their positive effects on human health after consuming.
Accurate standardization of PAC content is vital for establishing dosage guidelines for consumers, monitoring efficacy and shelflife of products and research studies.
