    Peptone is a spray dried powder, manufactured by a controlled enzymatic hydrolysis of animal tissue. The most commonly used enzymes are pepsin, papain and pancreatin. The latter containing trypsin.Pepsin will cut the peptide chain anywhere there is a phenylalanine or leucine bond.Papain cuts in the peptide chain adjacent to arginine, lysine, phenylalanine and glycine. Pancreatin has its action at arginine, lysine, tyrosine, tryptophan, phenylalanine and leucine bonds.The tissues are hydrolysed to produce straw coloured peptones which are highly nutritious and clearly soluble in water. Peptones contain a mix of peptides, free amino acids and growth factors.Due to the low sodium chloride concentration Formedium™Pepton is well suited for cultivation of yeast cells.Store dry at room temperature

Besides peptides and amino acids yeast extract also contains purine and pyrimidine bases, carbohydrates and water soluble vitamins of B group.Sodium Chloride concentration of Formedium™Yeast Extract is low and also therefore well suited for cultivation of yeast cells.Due to its carbohydrate content, typically 10%, yeast extract is not suitable for media intended for the study of sugar fermentation.Store dry at room temperature

    LB-Broth Low Salt, Lennox L Broth

    LB Broth Lennox is a nutritionally rich medium originally developed for growth and maintenance of recombinant E. coli strains. E. coli is grown to late log phase in LB Broth. These strains are generally derived from E. coli K12 which are deficient in B vitamin production. K12 has been ultimately modified by specific mutation into an auxothropic strain not capable of growth on nutritionally deficient medium. All nutritional requirements of E. coli strains are provided by LB Broth. Peptides and amino acids are abundantly present in Tryptone. Yeast extract is a rich source of amino acids, vitamins, nucleotides and carbohydrates. These nutritional elements in LB media, which otherwise the cell would have to synthesize,  support a luxurious growth of E. coli cells.

    Sodium ions for transport and osmotic balance are provided by Sodium chloride. The concentration of NaCl in LB Lennox is half the concentration of the LB Miller Broth formulation and ten times the concentration of LB Luria Broth formulation. These variations in Sodium chloride content make it possible to select the optimal salt concentration for a specific strain.

    Terrific Broth is rich nutritional medium developed by Tartoff and Hobbs supporting luxurious high density growth of E.coli and a higher yield of plasmid DNA compared to LB type media. Recombinant E. coli cells have an extended growth phase in Terrific medium.Terrific medium is used with glycerol as a carbon source. Unlike glucose, glycerol is not fermented to acetic acid.Tryptone and Yeast are present in the medium in elevated concentrations and provide nitrogen, vitamins and cofactors for a luxurious growth.Potassium phosphate is present in Terrific broth buffered to balance the pH and subsequently prevent cell death due to a drop in pH.Tartoff, K. D., and C. A. Hobbs, Improved media for growing plasmids and cosmid clones, Bethesda Research Laboratories, 9, 12, (1987). Sambrook, J,., E. F. Fritsch, and T.

    Yeast Nitrogen Base w/o Amino acids w/o Ammonium sulphate LoFlo is a low fluorescence YNB type medium.By omitting Folic acid and Riboflavine from the original YNB w/o Amino acids formulation the result is a very low fluorescence back ground medium.Yeast Nitrogen Base w/o Amino acids w/o Ammonium sulphate LoFlo is excellent for  whole-cell fluorescence experiments and because of its low fluorescence background the fluorescence of cells can be measured directly in the medium.Yeast Nitrogen Base w/o Amino acids w/o Ammonium sulphate LoFlo is well suited for intracellular pH measurements in cells expressing pHluorin in combination with Raman spectroscopy.Suspend 1.9 gram powdered medium in 1 litre distilled water Store dry at room temperature
