描述
从精确分期的胚胎中切下的小鼠或大鼠胚胎切片已专业安装在显微镜载玻片上，可以用于多种目的。这些部分特别适用于组织和器官发育，通过原位杂交表达DNA和RNA以及通过免疫组织化学对基因产物进行定位的研究。产品包装在密封的载玻片盒中，每个盒子包含10个显微镜载玻片，从不同水平的胚胎上切下20个矢状切面。
取出后，将胚浸入EmbryoFix™ （参见Products，目录号＃PF102）中固定3小时。这种固定方法可确保形态的出色保存，并减少组织中的抗原性。然后处理固定的组织以进行石蜡包埋。所有石蜡包埋embroyos在7微米矢状切割并安装在SuperFrost ® Plus或FISHERBRAND ProbeOn™显微镜载玻片（每载玻片2个连续部分）。装运前，所有切片均存放在4°C下。
Mouse or rat EmbryoSections, cut from accurately staged embryos, are professionally mounted on microscopic slides and are ready to use for a variety of purposes. The sections are especially suitable for studies of tissue and organ development, expression of DNA and RNA by in situ hybridization, and the localization of gene products by immuno-histochemistry. The products are packaged in sealed slide boxes and each box contains 10 microscope slides with 20 sagittal sections cut from various levels of the embryo.
Upon removal, embryos are immersion-fixed in EmbryoFix™ (cf. Products, Cat. #PF102) for 3 hours. This method of fixation ensures an excellent preservation of morphology and a minimal loss of antigenicity in tissue. Fixed tissues are then processed for paraffin embedding. All paraffin embedded embroyos are cut sagittally at 7 µm and mounted on Superfrost® Plus or Fisherbrand ProbeOn™ microscope slides (2 consecutive sections per slide). All sections are stored at 4°C before shipping.
