Lactose - sequential - high sensitivity - Enzymatic assay kit
Reference : K-LOLAC
This constitutes a significant improvement over existing commercially available lactose assay kits which typically overestimate lactose content in lactose-free samples due to the unselective hydrolysis of GOS by β-galactosidase.
Lastly, the sensitivity of the K-LOLAC assay kit has been doubled through the use of a cascade biochemical pathway, helping to significantly reduce the LOD and LOQ for the assay.

- World’s first sequential assay for lactose, i.e. improves accuracy and efficiency
- Contains a specific β-galactosidase for the selective measurement of lactose in dairy products
- Efficient pre-treatment step allows for accurate measurement of lactose in “low-lactose” and “lactose-free” dairy products
- Lower limit of detection (LOD) than any other commercially available enzymatic lactose detection method. LOD at 1,62 mg/L
- Very competitive price (cost per test)
