High purity Wheat Arabinoxylan (enzyme debranched; 30% Ara) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.

Prepared by controlled enzymic hydrolysis of wheat flour arabinoxylan. Essentially devoid of doubly substituted D-xylosyl residues.

Purity > 94%. Ara: Xyl = 30: 70.  Glucose, galactose and mannose < 2%.

Wheat Arabinoxylan (enzyme debranched, 30% Ara)
CAS: 9040-27-1

Preparation:
Medium viscosity wheat arabinoxylan was hydrolysed to the limit withBacteroides ovatus α-L-arabinofuranosidase (AXH-d3) to remove essentially all 1,3-α-linked L-Araf on doubly substituted D-xylosyl residues. The resultant arabinoxylan is essentially devoid of doubly substituted D-xylosyl residues. 

Stability:
> 5 years at room temperature 

Properties:
Purity: > 94% (dw basis). Glucose, galactose and mannose < 2%
Sugar Ratio: Arabinose:Xylose = 30:70
Viscosity: 0.4 cSt (1% w/v; Ostwald C-type viscometer, 30^oC)
Starch: < 0.01%
Beta-Glucan: < 0.01%
Protein: 0.5%
Moisture: 4.0%
Ash: 2.1%
