INTRODUCTION:

L-阿拉伯糖D-半乳糖检测试剂盒 L-Arabinose / D-Galactose Assay Kit  K-ARGA  
Enzymic kits for the determination of L-arabinose and D-galactose
are very slow. This is due to the low rate of natural chemical
“mutarotation” between the α- and β-anomeric forms of these
monosaccharides. Only the β-form is recognised by β-galactose
dehydrogenase. In incubations containing NAD+, L-arabinose
or D-galactose and β-galactose dehydrogenase, there is a very
rapid initial increase in absorbance due to the consumption of β
-L-arabinose or β-D-galactose, and this is followed by a very slow
approach to the end-point. This very slow approach results from
the very low rate of chemical “mutarotation” of the α-anomeric
conformation of these monosaccharides to the respective β-anomer.
Using technology developed by Megazyme (patent pending), a
galactose mutarotase has now been incorporated into the assay
format to rapidly catalyse this rate-limiting mutarotation step.
The result is very rapid analysis times of approximately 6 min for
D-galactose and approximately 12 min for L-arabinose (Figure 1).
