cGMP (Casein glycomacropeptide)
Rapid CDIATM cGMP kits are intended for quanlitative detection of casein glycomacropeptide in milk.
The cGMP is produced by enzymatic or bacterial induced degradation of the casein present in milk. This degradation takes place during the cheese manufacturing process, where specific proteases are added to act on the milk casein. Therefore its presence in milk is an indication of milk adulteration with whey. Other degradation processes (mostly related to the bacterial activity present in lactic products) are also capable of increasing the cGMP concentration but not as much as adulteration.
