Additional Selective and Differential Cell Culture Media
NEOGEN MacConkey Agar without Crystal Violet and Salt, 500 g
MacConkey Agar without Crystal Violet and Salt is used for the isolation and differentiation of Gram-negative enteric bacilli from specimens containing swarming strains of Proteus spp, and is not intended for use in the diagnosis of disease or other conditions in humans.MacConkey Agar is based on the bile salt-neutral red-lactose agar of MacConkey. The original MacConkey medium was used to differentiate strains of Salmonella typhosa from members of the coliform group. Formula modifications improved growth of Shigella and Salmonella strains. These modifications include the addition of 0.5% sodium chloride, decreased agar content, altered bile salts, and neutral red concentrations. The formula modifications improved differential reactions between enteric pathogens and coliforms.For more information visit https://www.neogen.com/solutions/Microbiology/macconkey-agar-without-crystal-violet-and-salt

NEOGEN Malt Extract Agar, 5 kg
Malt Extract Agar is used for the cultivation of fungi and is not intended for use in the diagnosis of disease or other conditions in humans. An acidic medium which will support the growth of most yeasts and molds whilst inhibiting most bacteria. It was first described by Thom and Church in 1926 in a study of Aspergillus spp. claiming the high carbohydrate content ensured rapid growth. Selectivity can be increased by further lowering the pH with the addition, after sterilization, of Lactic Acid (X037). It should be noted that excess heating of this medium together with its low pH can easily result in hydrolysis of the agar gel producing soft plates. Formula:Malt Extract - 30.0 g/LPeptone - 5.0 g/LAgar - 15.0 g/LFor more information visit https://www.neogen.com/solutions/Microbiology/malt-extract-agar
NEOGEN Violet Red Bile Agar (VRBA) (ISO), 5 kg
A medium for the enumeration of coliform organisms in food and dairy products according to ISO 4832:2006 and is not intended for use in the diagnosis of disease or other conditions in humans.The selectivity of the medium is due to the presence of bile salts and crystal violet. Lactose fermenters produce red/purple colonies often surrounded by a halo of the same color. Non-lactose fermenters produce pale colonies. Selectivity can be increased by incubation at 42-44°C.Formula:Yeast Extract - 3.0 g/LEnzymatic Digest of Animal Tissue - 7.0 g/LBile Salts - 1.5 g/LLactose - 10.0 g/LNeutral Red - 0.03 g/LCrystal Violet - 0.002 g/LAgar- 12.0 g/LFor more information visit https://www.neogen.com/solutions/Microbiology/violet-red-bile-lactose-agar-iso
NEOGEN Phenylethanol Agar, 500 g
Phenylethanol Agar is used with blood for the selective isolation of Gram-positive cocci in a laboratory setting. Phenylethanol Agar is not intended for use in the diagnosis of disease or other conditions in humans. Brewer and Lilley reported the addition of phenylethanol to a nutritive medium permitted growth of Gram-positive organisms, but markedly to completely inhibited growth of Gram-negative organisms. Phenylethanol Agar inhibits swarming of Proteus spp., and can be used to selectively isolate anaerobic bacteria from specimens with mixed flora. Phenylethanol Agar is specified for use in several reference methods.For more information visit https://www.neogen.com/solutions/Microbiology/phenylethanol-agar
NEOGEN Buffered Sodium Chloride - Peptone Broth pH 7.0, 10 kg
Buffered Sodium Chloride-Peptone Broth pH 7.0 is the diluent specified by the Harmonized Pharmacopoeia for the microbiological examination of non-sterile products andconforms to Harmonized USP/EP/JP Requirements in a laboratory setting. Buffered Sodium Chloride-Peptone Broth pH 7.0 is not intended for use in the diagnosis of disease or other conditions in humans.Buffered Sodium Chloride-Peptone Broth pH 7.0 is recommended by the Harmonized Pharmacopoeia (USP/EP/JP) for the microbiological examination of non-sterile products. The low level of peptone lessens the physiological shock experienced by microorganism when suspended in a diluent. The dual phosphate components create a buffered environment and sodium chloride maintains the osmotic balance.For more information visit https://www.neogen.com/solutions/Microbiology/buffered-sodium-chloride-peptone-broth-ph-7
NEOGEN R2A Agar, 5 kg
R2A Agar is used for the enumeration and cultivation of bacteria from potable water in a laboratory setting. R2A Agar is not intended for use in the diagnosis of disease or other conditions in humans. R2A Agar was developed by Reasoner and Geldreich for bacterial plate counts of treated potable water. R2A Agar is a low nutrient medium, and in combination with a lower incubation temperature and longer incubation time, stimulates the growth of stressed and chlorine-tolerant bacteria. Nutritionally rich media support the growth of fast-growing bacteria, and may suppress slow growing or stressed bacteria found in treated water. When compared with Tryptone Glucose Yeast Extract Agar or Plate Count Agar (Standard Methods Agar), R2A Agar reported improved recovery of stress and chlorine-tolerant bacteria from drinking water systems.For more information visit https://www.neogen.com/solutions/Microbiology/r2a-agar
