一般說明

环氧树脂包埋介质套装是电子显微镜中广泛使用的一种包埋介质。包埋配方最初由Luft发布(1961年),既适用于植物组织,也适用于动物组织。由于树脂粘度低,所以能比Araldite和其他聚合物更快地渗透到组织样本中。加入十二碳烯基琥珀酸酐(DDSA)、甲基萘二酸酐(MNA)和加速剂2,4,6-三(二甲氨基甲基)苯酚(DMP-30)后,它能在低温下快速且均匀地硬化。固化时可能产生细微收缩。此套装适用于包埋各种组织,通过针对特定组织类型调配使用两种不同的酸酐硬化剂(DDSA和MNA),可实现广泛的样品硬化。

應用

环氧树脂包埋介质套装已用于以下应用:

  • 研究NDRG2(一种关键结肠上皮屏障调节因子)在肠道稳态维持和结肠炎相关肿瘤发展中的作用
  • 研究聚合物支架纳米纤维与生长细胞的相互作用
  • 研究鸭胚后发育期间血液–脾脏屏障的形态特征
  • 了解NOD1/NOD2受体在具核梭杆菌介导的中性粒细胞胞外陷阱中的作用。

特點和優勢

  • 用于 包埋多种组织的优良介质,包括植物和动物 组织。
  • 有助于快速包埋(少于3小时)。
  • 低粘度有助于组织快速渗透。
  • 容易获得理想的硬度,以适应特定的组织类型。
