Immunoelectron microscopy of mammary gland tissue from lactating rats with the trans-Golgi network identified by immunogold labeling of TGN38, a transmembrane trans-golgi protein. Note that trans‐Golgi cisternae in lactating mammary cells contain large amounts of casein and other milk proteins and are grossly expanded due to the osmolarity of the secreted fluid.

利用免疫电子显微镜对泌乳大鼠乳腺组织进行观察，通过TGN38（跨膜转高尔基蛋白）的免疫金标记识别转高尔基网络。值得注意的是，泌乳乳腺细胞中的转高尔基池含有大量的酪蛋白及其他乳蛋白，由于分泌液的渗透压，这些池体显著扩张。
