Human duodenal epithelium, at the level of the crypt. Fixation was carried out inbuffered formal-calcium. Peroxisomes are stained with DAB by their catalase activity at pH 10.5, postosmicated and embedded in epon. 2 µm plastic section.)

Peroxisomes are the very small brown granules located between the brush border and the elongated epithelial nuclei (unstained). A few rounded goblet cells are recognized. In the subepithelial capillaries, 5 large black structures are erythrocytes that reacted with DAB by the peroxidatic activity of hemoglobin.

人类十二指肠上皮组织，位于隐窝水平。固定处理采用缓冲的钙盐溶液。通过pH 10.5下过氧化物酶的催化活性，利用DAB染色过氧化物酶体，随后进行过氧化氢化处理并嵌入环氧树脂中。切片厚度为2微米。过氧化物酶体是位于刷状缘与延长型上皮细胞核之间（未经染色）的极小棕色颗粒。识别出少数圆形的杯状细胞。在亚上皮层的毛细血管中，有5个大型黑色结构为红细胞，它们通过与DAB的过氧化酶活性反应而呈现。
