Safety Data Sheet
Generic tools to assess genuine carbohydrate specific effects on in vitro immune modulation exemplified by β-glucans.

Rieder, A., Grimmer, S., Aachmann, F. L., Westereng, B., Kolset, S. O. & Knutsen, S. H. (2013). Carbohydrate Polymers, 92(2), 2075-2083.

Even if carbohydrate preparations from plant/fungal sources have a high degree of purity, observed immune-stimulation may be caused by minute sample contaminations. Using the example of different β-glucans we present a range of analytical tools crucial for validation of possible immune-stimulatory effects. Two yeast (MacroGard and Zymosan) and one cereal β-glucan (CBG40) increased IL-8 secretion by HT-29 cells considerably. Degradation of the β-glucan samples with β-glucan specific enzymes did hardly influence the effect of Zymosan and CBG40 but significantly decreased the effect of MacroGard. Stimulation of IL-8 secretion by CBG40 and Zymosan was hence not due to their β-glucan content. Instead, the effect of the CBG40 sample was due to low levels of LPS despite the inability of the known LPS inhibitor Polymyxin B to supress its stimulatory effect. We conclude that targeted enzymatic degradation of samples is a powerful validation tool to investigate carbohydrate specific immune-modulation.
