Arabinoxylan (Wheat Flour) (P-WAXYI, P-WAXYL, P-WAXYM, P-WAXYH)

What are the average molecular weights of the high, medium and low viscosity arabinoxylans P-WAXYL, P-WAXYM & P-WAXYH?
MW’s of arabinoxylans are provided on the individual product datasheets: Product Page (P-WAXYL) Product Page (P-WAXYM) Product ...

Does your Wheat Arabinoxylan have any ferulic acid substitutions?
We use alkali during the extraction of wheat arabinoxylan.  We believe that this breaks the diferulate bridge and releases the ferulic acid.  We also sup...

Are your arabinoxylans and rhamnogalacturonans O-acetylated?
No. The purification of each of these (except the insoluble wheat arabinoxylan) involves an alkali step.  This results in deacetylation of the polymer. ...

I wish to include a solubilised xylan in polyacrylamide gels to perform xymograms and wondered if you might have a product to suit that need.
Possibly the best substrate we could offer for this is Wheat Arabinoxylan (undyed) or Beechwood Xylan.  However, if you prefer a dyed substate, I would re...

What is the reason for wetting with ethanol and is it really necessary to dissolve arabinoxylan at 100˚C? We have good experience with dissolution in water at ambient temperature.
The alcohol helps avoid lumping of the polysaccharide when the water is added.  Arabinoxylan can be dissolved at ambient temperature, so if this is what y...

The xylose to arabinose ratio is given on the arabinoxylan data sheet. Is this ratio liable to fluctuation across different batches?
We believe that the A/X ratio of arabinoxylan from wheat would not vary much between different wheat samples. We have not seen any variation. Produ...
