The L-Arabinose/D-Galactose test kit is a simple, reliable and accurate UV method for the measurement and analysis of L-arabinose and/or D-galactose in various materials including foods, feeds, beverages and plant products. 

Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC. 

Suitable for manual, auto-analyser and microplate formats.

UV-method for the determination of L-Arabinose and D-Galactose 
in hydrolysed plant products

                                      (galactose mutarotase)
(1) α-L-Arabinose / α-D-galactose ↔ β-L-arabinose / β-D-galactose

                      (β-galactose dehydrogenase)
(2) β-L-Arabinose + NAD+ → L-arabinonic acid + NADH + H+
                    (β-galactose dehydrogenase)
(3) β-D-Galactose + NAD+ → D-galactonic acid + NADH + H+


Kit size:                            115 assays (manual) / 1150 (microplate)
                                          / 1150 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
