DESCRIPTION
Med Biosciences Glycerol Buffered Saline (GBS) Medium is recommended for use in qualitative procedures for collection, transportation, and preservation of fecal clinical specimens.
GBS medium is one of the earliest media developed for transport of stool specimens. It is especially suitable for preserving the viability of Salmonella and Shigella species and Escherichia coli in stool specimens.
The medium contains Glycerol-Phosphate buffer to maintain a near neutral pH. This is necessary to preserve certain enteric pathogens (Salmonella and Shigella species and Escherichia coli ) in stool specimens. Phenol Red is a pH indicator which changes the medium to a yellow when the medium is acidified by the action of these enteric bacteria. Note: GBS medium is not suitable for Vibrio cholera, Campylobacter species or Yersinia enterocolitica.
GBS medium is produced under highest manufacturing standards. It is formulated from highly pure molecular-grade chemicals in autoclaved 18.2 mega Ω-cm DNase-RNase-free deionized water.
GBS Medium is sterilized by autoclaving. The medium is a clear red liquid and is negative for microbial growth after 48 hours at 37á´¼C.
Our medium is provided in Sterile, DNase/RNase-free Medical Grade PET/PETG, transparent, and leak-proof bottles of different sizes (100, and 250 mL).
COMPOSITION:
The medium is composed of a phosphate buffer solution containing Sodium Chloride, Di-sodium hydrogen phosphate, Potassium dihydrogen phosphate with Phenol red and Glycerol (pH 7.2 ± 0.2).
