Meaning and Definition

A chemical staining solution used in microbiology to differentiate bacteria based on their cell wall structure, a key step in the Gram stain procedure.

Specifically refers to the crystal violet-iodine complex solution used as the primary stain in the Gram staining technique, which classifies bacteria as either Gram-positive (retaining the stain) or Gram-negative (losing the stain).

FAQ

Frequently Asked Questions

No. Gram's solution is specifically the primary stain (crystal violet and iodine). The 'Gram stain' refers to the entire multi-step procedure which includes Gram's solution, a decolorizer, and a counterstain.

It is named after Hans Christian Gram, the Danish bacteriologist who developed the staining technique in 1884.

No. It is only effective as part of the full Gram stain protocol. Using it alone would stain all bacteria purple without differentiation.

Extremely rarely. Its use is almost entirely confined to microbiology, clinical pathology, and related laboratory science fields.
