產(chǎn)品貨號：ZZK-K-ARGA
產(chǎn)品品名：L-阿拉伯糖/D-半乳糖檢測試劑盒
英文品名：L-Arabinose / D-Galactose Assay Kit
規(guī)格型號：115 assays (manual) / 1150 assays (microplate) / 1150 assays (auto-analyser)
A simple, reliable and accurate UV method for the measurement ofL-arabinose and/or D-galactose in various materials including foods,feeds, beverage and plant products.
INTRODUCTION:
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).
KITS:
Kits suitable for performing 115 assays in manual format (or 1150 assays
in microplate or auto-analyser formats) are available from Megazyme.
