Description of Xylan

Xylan represents the main hemicellulose component in the secondary plant cell walls of flowering plants. Xylan is a polysaccharide made from units of xylose and contains predominantly β-D-xylose units linked as in cellulose.

Two different Xylan fractions are extracted from spruce wood using an alkaline process (AGX-A) and a hydrothermal process by subcritical water (AGX-H). AGX-A shows lower relative glucuronation and higher arabinosylation compare with AGX-H. These differences in substitution may arise from the different extractability of distinct Xylan populations in softwoods or be induced by the extraction process. mGlcA substitutions do not affect significantly the conformational space of the Xylan backbone, neither in their protonated nor deprotonated state[1].

Protocol of Xylan

Kinase experiment:

Arabinoglucuronoxylan (AGX) is extracted and purified from Norway spruce (Picea abies) secondary cell walls using two complementary processes: (i) alkali extraction after delignification (AGX-A) and (ii) subcritical water extraction and enzymatic purification (AGX-H). The monosaccharide composition of the Xylan is analyzed after acid methanolysis (1 M TFA, 3h, 100°C) and high-pH anion-exchange chromatography with pulsed amperometric detection[1].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
