Amies; buffered glycerol-saline is suitable for E. coli, Salmonella, Shigella, and Y. enterocolitica but not for Campylobacter and Vibrio). Insert swab 1-1.5 inches into rectum and gently rotate. Place both swabs into the same tube deep enough that medium covers the cotton tips. Break off top portion of sticks and discard.
Does anyone know what is the viscosity and dielectric constant for phosphate buffered saline pH 7.4? I'm using PBS (pH 7.4) as dispersant for size and zeta potential analysis. Aims: To evaluate the suitability of using sterile water and phosphate-buffered saline (PBS) for preservation of bacteria pathogenic to plants or humans. Methods and results: The stationary-phase bacterial cells collected from rich agar media were transferred to 10 ml of sterile water or PBS (pH 7.2) containing KH2PO4, 15.44 microm; NaCl, 1.55 mm; Na2HPO4, 27.09 microm in a screw-cap tube. Normal, buffered, HSA, and 10% glycerin saline diluents contain 0.4% Phenol, a preservative that inhibits microbial growth. Two neck sizes are available, providing a choice of stopper diameter. The second number after the vial size is the outer diameter of the top of the vial in millimeters. Normal Saline/Phenol (Phenolated Saline) Buffered glycerol It is particularly useful for fluorescence-labeled specimens since "anti-fading" reagent can be supplemented with glycerol to increase the half-life of the fluorescence signal. In general, buffered saline (e.g. phosphate, Tris or HEPES buffered saline) is added to glycerol to yield a 70%-80% glycerol solution).

Methods and Results: The stationary‐phase bacterial cells collected from rich agar media were transferred to 10 ml of sterile water or PBS (pH 7·2) containing KH 2 PO 4 , 15·44 μ m Jul 14, 2012 · Tris-buffered saline (TBS) is isotonic, notoxic buffer used in some biochemical techniques that is maintain the pH within a relatively narrow range. Tris-HCl is commonly used to make TBS buffers and has a slightly alkaline buffering capacity in the 7–9.2 range.

PBS (phosphate buffered saline) is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions which, when diluted to a 1X working concentration, contains 137 mM NaCl, 2.7 mM KCl, 8 mM Na 2 HPO 4, and 2 mM KH 2 PO 4. Each 10X PBS solution is ready to use upon dilution to the desired concentration. Phosphate-buffered saline (abbreviated PBS) is a buffer solution commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH. Buy and get information for Buffered Glycerol Saline Base, M204, Microbiology, Dehydrated Culture Media, General, Animal based Media, Bacterial
