Sorbitol Dehydrogenase (SDH) Assay Kit                                                                                                                                                      Price

Product Description: Sorbitol dehydrogenase (SDH), found in organisms from bacteria to humans, converts sorbitol, the sugar alcohol form of
glucose, to fructose, and the zinc-dependent reaction uses NAD+ as a cofactor. The enzyme along with
aldose reductase constitutes the polyol
pathway
, which connects glucose and fructose metabolism. Organs abundant in SDH activity include the liver, kidney, lens and seminal vesicle.
Since SDH activity promotes the formation of NADH, the redox change induced by elevated SDH may have a pathogenic role in certain disease
state, making SDH a potential therapeutic target. In addition, SDH has a close evolutionary relationship with
alcohol dehydrogenase (ADH). Our
non-radioactive colorimetric SDH assay is based on the reduction of the tetrazolium salt INT in a NADH-coupled enzymatic reaction to formazan,
which is water-soluble and exhibits an absorption maximum at 492 nm. The intensity of the red color formed is increased in the presence of
increased SDH activity. The kit is stable for at least one year under proper storage and handling conditions.
