Description
Digalacturonic acid (DGA), derivedin vivofrom pectin catabolism, is used for the co-crystallization of enzymes such as proteinase K. It is used in galacturonic acid metabolism research as a substrate to identify, differentiate and characterized endo- and exopolygalacturonase(s) and gluconase(s). DGA is used to study the transport of oligogalacturonides by systems such as the TogMNAB ABC transporter.

产品介绍：
A2 聚糖存在于许多哺乳动物糖蛋白上，包括血清转铁蛋白和纤维蛋白。本品通常使用HPLC和糖苷酶消化的组合，通过肼分解从纤维蛋白释放的寡糖池中纯化。
形式：通过离心蒸发从水溶液中干燥。含有铵盐，可稳定防止脱唾液酸化。
样品数量：通常，根据荧光计、HPLC 或质谱仪的灵敏度，可以检测 100 fmol 至 10 pmol的 A2 2-AA 聚糖。
检波荧光检测：360nm激发波长，425nm发射波长。
说明：
标记的聚糖混合物可通过各种 HPLC（高压液相色谱）方法使用HPLC 色谱柱进行分离和分析。
色谱柱是一种特别强大的工具，用于纯化和分析来自复杂聚糖混合物的标记的低聚糖。聚糖也可以通过质谱、电泳和各种类型的光谱进行分析，请联系我们以获取有关您的特定应用的建议。
Product description：
A2 glycan is found on many mammalian glycoproteins including serum transferrin, and fibrin. This product is typically purified from the oligosaccharide pool released from fibrin by hydrazinolysis using a combination of HPLC and glycosidase digestion.
Form: Dried by centrifugal evaporation from an aqueous solution. Contains ammonium salt to stabilise against desialylation.
Number of Samples: Typically, 100 fmol to 10 pmol of the A2 2-AA glycan can be detected, dependent on the sensitivity of the fluorometer, HPLC or mass spectrometer.
Detection Fluorescence detection: 360 nm excitation wavelength, 425 nm emission wavelength.
Explanation：
Labeled glycan mixtures may be separated and analysed by a variety of HPLC (high pressure liquid chromatography) methods using HPLC columns.
Columns are an especially powerful tool for the purification and analysis of labeled oligosaccharides from complex glycan mixtures. Please contact us for advise regarding your particular application.

应用
对橙皮苷和橙皮素（甙元）与 DMPC 脂质体的行为研究发现，甙元穿透更深，与“膜”结合更强。这可能解释了一般生物类黄酮苷元生物利用度较好的原因。

Application
Studies of the behavior of hesperidin and hesperetin (the aglycone) with DMPC liposomes find the aglycone penetrates more deeply and binds more strongly to the “membrane.” This may explain the better bioavailability of bioflavonoid aglycones in general.
