    Doxycycline is a bacteriostatical Tetracycline like antibiotic. The antibiotic is effective against both gram-positive and gram-negative bacteria. It binds reversible to the ribosomal 30 S unit, preventing binding of aminoacyl transfer RNA and hence inhibiting protein synthesis. Doxycycline is an effective repressor of the TetO7 promoter system. Media containing 10 micro-gram Doxycycline effectively repress the TetO7 promoter.

    Hydroxyurea is an anti-neoplastic which Inactivates ribonucleoside reductase by forming a free radical nitroxide that binds a tyrosyl free radical in the active site of the enzyme. This blocks the synthesis of deoxynucleotides, which inhibits DNA synthesis and induces synchronization or cell death in S-phase.

    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.

    The absence of phosphate (KH2PO4) provides the possibility to include alternative sources of phosphate, like P32 labeled components, or to select an optimal concentration of phosphate for certain yeast cell lines. By omitting Potassium DiHydrogen Phosphate (KH2PO4), not only Phosphate (PO4-3) but also Potassium (K ) is omitted. As a result yeasts are not only limited in Phosphate, but also in Potassium. This might cause problems in osmo-molarity and intercellular Potassium ion concentrations finally resulting in poor cell growth and low yields. To avoid this problem an extra 550 mg/l (7.35 mM) of KCl is added. By adding this concentration of KCl the original concentration of K as present in YNB is restored. The extra addition of Chlorine is in almost all cases no problems to your cells. Suspend 1.5 gram powdered medium in 1 litre distilled water Store dry at room temperature

    Yeast Nitrogen Base without amino acids (YNB w/o AA) is used for selecting yeasts based on amino acid and carbohydrate requirements. In Yeast Nitrogen Base with out amino acids Ammonium sulphate is included as a readily available nitrogen source for nitrogen assimilation. The medium includes all other vitamins, mineral salts and trace elements required for a vigorous growth of yeast cells. Compared to full Yeast Nitrogen Base medium, Yeast Nitrogen Base without amino acids lacks Histidine, Methionine and Trypthophan. In combination with Drop Out medium supplement mixtures  Yeast Nitrogen Base without Amino acids provides an excellent medium to cultivate and to select auxothophic strains of yeast that requires the addition of essential nutrients like amino acids and/or vitamins. The addition of a carbon source like glucose, galactose or raffinose is required. Synthetic Dextrose Minimal medium (SD medium) and Synthetic Complete medium (SC medium) are based upon Yeast Nitrogen Base w/o amino acids and are complemented with glucose, galactose and raffinose as carbon sources.
