Negative staining method stains the background of your sample while leaving the actual bacterial cells untouched, allowing the cells to be quite visible on a dark background. Negative staining does not require the bacterial cells to be heat-fixed and is especially useful for cells that are susceptible to damage during the heat fixation process, such as cryptococcus neoformans. Often used to determine cell size and examine cell arrangement. Kit includes: Formalin-Nigrosin Solution, Congo Red, and Hydrochloric Acid. All are packaged in convenient 1 oz/30ml dropper dispensing bottles, with SDS for each. For laboratory use only. Keep out of reach of children.
