Gram Staining Kits

Gram staining kits are available from several suppliers to differentiate between Gram-negative and Gram-positive classifications of bacteria. This grouping arises due to the differential retention of the crystal violet stain within the bacterial cell wall. Gram-positive bacteria feature a thicker peptidoglycan layer, which retains crystal violet and appears blue or violet in color. Gram-negative cell walls consist of a thinner peptidoglycan layer sandwiched between an outer and inner cell membrane. This results in the loss of the primary stain during decolorization, ultimately leading to reddish or pink coloration. Visit the Gram staining kit suppliers for more details, including kit components.
