Application
聚集蛋白聚糖是软骨结构和关节功能的关键成分。 研究人员正在研究其合成和降解,以了解其在关节损伤疾病和衰老过程中软骨退化中的作用。
Biochem/physiol Actions
这种分子产生一种刚性、可逆、耐压缩的可变形凝胶。 它与透明质酸结合形成非常大的大分子复合物,该复合物具有增加的流体动力学体积和显著增加的溶液相对粘度(30-40%)。
Preparation Note
该产品从关节软骨中提取,经过化学纯化、水透析,并在冻干前进行0.2 μm过滤。 一旦冻干,这种粉末基本上不含盐。 产品在水中的溶解度为 2 mg/mL。
Other Notes
聚集蛋白聚糖是软骨细胞外基质的主要结构蛋白聚糖。 它是一种大蛋白聚糖,分子量大于 2,500 kDa,由连接核心蛋白的大约 100-150 条氨基聚糖链组成。 这些氨基聚糖链大多为软骨素/硫酸皮肤素。聚集蛋白聚糖包含G1、G2 和 G3三个球状结构域,它们与聚集和透明质素(hylauronan )结合、细胞粘附和软骨细胞凋亡有关。
Disclaimer
在 -20°C 储存。按供货时的状态储存,如果储存得当,这种粉末在 3 年内几乎没有分解。
