10X Phosphate Buffered Saline (PBS), Sterile, Dulbecco's Formula, without Magnesium and Calcium, MP Biomedicals

Catalog Number: (IC091960454)

Supplier: MP Biomedicals

Description: Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions: 1. Serves as an irrigating, transporting and diluting fluid while maintaining intra- and extracellular osmotic balance; 2. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism; 3. Combined with a carbohydrate, such as glucose, provides the principal energy source for cell metabolism; 4. Provides a buffering system to maintain the medium within the physiological pH range (7.2 - 7.6)

2-Mercaptoethanol ≥98%, liquid cell culture reagent

Supplier: MP Biomedicals

Description: Storage: Room Temperature
2-Mercaptoethanol is a hybrid of ethylene glycol and 1,2-ethanedithiol. It is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals. It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its diminished vapor pressure, its odour, while unpleasant, is less objectionable than related thiols.
2-Mercaptoethanol is used to reduce disulfide linkages in solubilizing proteins for gel electrophoresis (typically used in SDS-PAGE sample buffer at 5% concentration). Also it reduces excess oxidative polymerization of catalysts. Cleaving intermolecular (between subunits) disulfide bonds allows the subunits of a protein to separate independently on SDS-PAGE. Cleaving intramolecular (within subunit) disulfide bonds allows the subunits to become completely denatured so that each peptide migrates according to its chain length with no influence due to secondary structure. In solution, 2-mercaptoethanol is readily oxidized in air to a disulfide, especially at alkaline pH. Because of this property, it is widely used to protect proteins, enzymes in particular, from becoming inactive. An excess of 2-mercaptoethanol (generally used at 0.01 M) will maintain the protein thiol groups in their reduced state.
