悬赏5流星已解决
我们现在参照ISO 19344:2015 去做益生菌产品中活菌染色和计数的技术开发方案。
标准原文如下:
“These beads with known concentration and fluorescence intensities shall be used to demonstrate appropriate detection of relevant wavelengths and intensities of the emitted light as well as to document calibration status. The use of standard beads also provides the ability to make accurate comparisons of data from sample to sample, from day to day or from laboratory to laboratory.”
益生菌的长宽一般为(0.5~1.2)μm×(1.0~10.0)μm,我们用SYTO24和PI双染来判定细菌死活。
请大家推荐一些可用的染色微球的产品,万分感谢!!

不是,微球的作用就是为了用于计数和仪器性能校准。
