Negative Stain

Often used to determine cell size and examine cell arrangement. Negative staining stains the background while leaving bacterial cells untouched. The result is clear cells against 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. Kit includes 1 oz (30mL) dropper bottles of Formalin-Nigrosin Solution Hydrochloric Acid, Congo Red, and Hydrochloric Acid, and SDS for each. For laboratory use only. Keep out of reach of children.

  • 30 ml Formalin-Nigrosin Solution Hydrochloric Acid 1%
  • 30 ml Congo Red 1% Aqueous Solution
  • 30ml Hydrochloric Acid 1%
  • Safety Data Sheets for each
