General description
Lactose is a dissacharide formed by the condensation of one galactose and one glucose molecule. Lactose is the major sugar in the milk of most species, typically present between 2-8%. The enzyme lactase hydrolyzes lactose to its constituent monosaccharides. In neonates, glucose released via the action of lactase is a major energy source.
Application
Lactose Assay Kit has been used to measure lactose content in milk.
Suitable for the direct measurement of lactose levels in various biological samples (serum, plasma, other body fluids, food, growth media, etc.)
Biochem/physiol Actions
In this assay, lactose concentration is determined by an enzymatic assay, in which lactose is converted to galactose and glucose. The galactose is subsequently oxidized, resulting in a colorimetric (570 nm)/ fluorometric (λex = 535 nm/λem = 587 nm) product, proportional to the lactose initially present. This kit is suitable for use with various biological samples and has a linear range of detection between 0.2-1.0 nmole lactose for the fluorometric assay and 2-10 nmoles lactose for the colorimetric assay.

Breastfeeding confers robust benefits to offspring development in terms of growth, immunity, and neurophysiology. Similarly, improving environmental complexity, i.e., environmental enrichment (EE), contributes developmental advantages to both humans and laboratory animal models.
