Gram-Hücker R Kit To differentiate Gram-positive from Gram-negative Bacteria

Catalog Number: (720-0350)
Supplier: RAL
Description: Gram-Hücker staining is based on the same principle than the Gram-Nicolle staining. The structure of the bacterial walls and their permeability to alcohol help differentiate the Gram-negative bacteria from the Gram-positive ones. In this technique, Carbolic Gentian Violet is replaced by Crystal Violet Oxalate (that does not require filtration) and Ziehl-Carbolic Fuchsin by Safranin.

Experimentation kits, bacterial gram staining

Catalog Number: (BE-202)
Supplier: G-Biosciences
Description: The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.
