      Product Detail  


    Application: Alkaline lake blue BB is mainly used for dyeing cotton, acrylic fiber, linen, and silk, with poor fastness and a sun fastness of 2-3 levels. It is also used for paper dyeing, bamboo and wood coloring, as well as manufacturing ink and color lakes. It can also be used for dyeing biological bacterial tissues. It can be used for dyeing hemp, silk fabrics, paper, and coloring bamboo and wood. It can also be used for manufacturing ink and color lakes, as well as staining biological and bacterial tissues. It can be mixed with alkaline purple 5BN and yellow cyclodextrin in a ratio of 78:13:9 to form alkaline blue. Application: A non-toxic dye, with blue color for oxidation and colorless for reduction When staining yeast live cells, due to cellular metabolism, the cells have strong reducing ability, which can cause methylene blue to change from a blue oxidized type to a colorless reduced type. However, for cells with weak metabolism or dead cells, they have no or extremely weak reducing ability and are stained blue or light blue by methylene blue This method can not only observe the morphology of yeast cells, but also be used to identify dead and live cells of yeast
