产品介绍

结缔组织狭义上是指其含有的三种纤维：胶原纤维、网状纤维、弹力纤维，而胶原纤维（collagen fiber）是分布最广、含量最多的一种纤维。Masson三色染色又称马松染色，是结缔组织染色中最经典的一种方法，是胶原纤维染色权威而经典的技术方法。所谓三色染色通常是指染胞核和能选择性的显示胶原纤维和肌纤维。该法染色原理与阴离子染料分子的大小和组织的渗透有关：分子的大小由分子量来体现，小分子量易穿透结构致密、渗透性低的组织；而大分子量则只能进入结构疏松的、渗透性高的组织。然而，淡绿或苯胺蓝的分子量都很大，因此 Masson 染色后肌纤维呈红色，胶原纤维呈绿色（淡绿）或蓝色（苯胺蓝），主要用于区分胶原纤维和肌纤维。改良Masson三色染色与常规Masson三色染色的区别在于采用天青石蓝苏木素淡染细胞核。其特点在于分化时间短（1~2min）；色彩清晰鲜艳；适用范围广，适宜于组织的石蜡切片、冰冻切片等染色；所染切片保存时间长且不易褪色。胶原纤维呈蓝色，肌纤维、胞质、纤维素、角蛋白和红细胞呈红色，胞核呈蓝褐色，主要用于区分胶原纤维和肌纤维。 I774801
