番红(也称作番红O或基本红2)是个用在组织学和细胞学的生物染色剂。番红在一些染色实验计划表中用作复染剂，将所有的细胞核染成红色。这在革兰氏染色和内孢子染色都是典型的复染剂。它也可以被用来检测软骨、黏蛋白和肥大细胞的颗粒。

Safranin (also Safranin O or basic red 2) is a biological stain used in histology and cytology. Safranin is used as a counterstain in some staining protocols, colouring all cell nuclei red. This is the classic counterstain in both Gram stains, and endospore staining. It can also be used for the detection of cartilage, mucin and mast cell granules.
