油红O

Oil Red O对脂质物质染色，脂质呈橙红色。它也可标记液泡，尤其是在ALL-L3(急性淋巴细胞白血病)或伯基特淋巴瘤/白血病中观察到。Oil Red O对新鲜样本染色，因为酒精固定除去了脂质物质。Oil Red O是一种脂肪染色剂。它是用来染色和可视化脂肪的大概位置。

可以使脂质，肌肉纤维和肺泡巨噬细胞染色的试剂。

用途

Oil Red O已可用于：

用于肝脏切片的组织学分析染色

用于细胞内脂质含量的测定

染色主动脉以检查动脉粥样硬化病变

Oil Red O已可用于细胞内脂滴和含脂液泡的染色。

Oil Red O stains lipids and is commonly used to analyze muscle fibers. Studies have combined using muscle cross sections with immunofluorescence microscopy to visualize and identify muscle fiber type specific intramyocellular lipids (IMCL) using Oil Red O. Sertoli cell research reports using Oil Red O staining to study the association between lipid droplet formation and the phagocytosis of apoptotic spermatogenic cells in vitro. Oil Red O does not stain unesterified cholesterol and can also be used to stain alveolar macrophages.
An agent that stains lipids, muscle fibers and alveolar macrophages.

Application

Oil Red O has been used for the staining of lipid droplets and lipid-containing vacuoles in cells.

Oil Red O has been used:

for staining liver sections in histological analysis

for the quantification of lipids in cells

to stain aorta to examine atherosclerotic lesions
