Abstract
Poly-beta-hydroxybutyrate granules exhibited a strong orange fluorescence when stained with Nile blue A. Heat-fixed cells were treated with 1% Nile blue A for 10 min and were observed at an excitation wavelength of 460 nm. Glycogen and polyphosphate did not stain. Nile blue A appears to be a more specific stain for poly-beta-hydroxybutyrate than Sudan black B.
摘要
用尼罗蓝A染色时，聚-β-羟基丁酸酯颗粒呈现出强烈的橙色荧光。将热固定的细胞用1%尼罗蓝A处理10分钟，并在460nm的激发波长下观察。糖原和多磷酸盐未被染色。尼罗蓝A似乎是一种比苏丹黑B对聚-β-羟基丁酸酯更具特异性的染色剂。
