The Gram Stain Kit is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria. Gram staining is a common technique used to differentiate between two large groups of bacteria based upon cellular wall composition, coloring Gram-positive and Gram-negative groups red or violet. Gram-positive bacteria will stain violet by retaining crystal violet in a thick layer of peptidoglycan in their cell walls. Gram-negative bacteria will stain red because crystal violet in not retained in the thinner peptidoglycan wall during the decoloring process.

Gram Positive Bacteria: Blue
Gram Negative Bacteria: Red
Other Tissue: Yellow
Nuclei: Red
