细菌粘附

细菌黏附

 

背景 

针对细菌粘附实验的测试方法，用户可以按特定需求，灵活应用标准操作步骤（预孵育，给样，冲洗等）和测试终点（生物化学，分子生物学，组学，细胞成像等），开发自己的测试方法和标准操作规范。与标准化的毒理学测试方法相比，该方法可以选择已知的参考物质作为阳性和阴性对照。

 

描述 

近期的科学研究证实细菌对人类上皮和表皮有重要的影响，因为三维重建组织模型可以被共生菌或病原体细菌粘附，所以此类模型可以作为研究上皮/皮肤微生物的工具。（请注意订购没有抗生素的特定培养基）

应用实例

  • 研究细菌粘附机理
  • 研究和治疗念珠菌病

 

模型 

EpiSkinTM 表皮模型（大孔径）

SkinEthicTM RHE 表皮模型

SkinEthicTM HCE 角膜模型
