A propos de cet article
For quantitative determination of lactose and evaluation of drug effects on lactose metabolism.
- Linear detection range 17 to 2000 μM lactose for colorimetric assays and 6 to 100 μM for fluorimetric assays
Lactose (C12H22O11), also called milk sugar, is a disaccharide that consists of β-D-galactose and α/β-D-glucose through a β1-4 glycosidic linkage
BioAssay Systems’ assay uses specific enzyme-coupled reactions in which lactose is cleaved and the resulting galactose forms a colored product. The color intensity at 570nm or fluorescence intensity at 530nm/585nm is directly proportional to the lactose concentration in the sample.
Lactose is the major sugar and makes up 2–8% of milk. Simple, direct and high-throughput assays for lactose determination find wide applications.
