DSS诱导大鼠溃疡性结肠炎模型

作者:翌圣生物科技(上海)股份有限公司 2024-07-12T00:00 (访问量:26071)

葡聚糖硫酸钠盐(Dextran Sulfate Sodium Salt, DSS)是一种聚阴离子衍生物,其诱导结肠炎模型的机制虽仍未十分明确,但通常认为与巨噬细胞功能失调、肠道菌群失调、DSS对结肠上皮的毒性作用、细胞因子在DSS结肠炎模型的发病中起重要作用等机制有关。

 

 

实验案例1

实验动物:大鼠,1周龄,100 g;

实验步骤:5%的DSS,3.5 mL/100 g每日灌胃,灌胃2周,HE染色;

实验结果:UC大鼠的结肠长度低于健康大鼠;结肠黏膜异常,存在大量炎症细胞。

实验案例2

实验动物:大鼠,8周龄,200 g;

实验步骤:饮用3.5% 浓度的DSS,连续饮用10天,HE染色;

实验结果:结肠黏膜异常。

实验案例3

实验动物:大鼠,7周龄,300-320 g;

实验步骤:饮用7天 2.0 % 浓度的DSS后,饮用7天蒸馏水,共4个周期,HE染色;

实验结果:结肠黏膜异常。

翌圣DSS产品优势

翌圣生物提供高品质DSS(Cat.NO:60316ES,MW:36000~50000),具有以下优势:

1. 高纯度(>98%),硫含量17-19%,游离硫<0.2%,大量数据文献支持,广泛应用于UC模型的构建。

2. 多种属动物中均可造模:小鼠、大鼠、斑马鱼、猪、果蝇;

3. 症状表现与人UC极度相似:可用于研究急、慢性结肠炎的发生发展机制,也可用于药物的药效研究。

4. 简单易行,成模率高,重复性强

5. 联合氧化偶氮甲烷 (azoxymethane, AOM)用药,可用于诱发结肠炎相关性癌症 (colitis associated cancer, CAC) 动物模型,成功模拟IBD诱发CAC的过程。 

建模效率与进口产品一致,产品价格低至进口价格的1/3,大量现货库存。
