Beschreibung: SDS is an detergent typically used to solubilize and denature proteins for electrophoresis. SDS has also been used in large-scale phenol extraction of RNA to promote the dissociation of protein from nucleic acids when extracting from biological material. SDS is used in Protein Electrophoresis & Blotting.

Beschreibung: Storage: +4 °C
Pyruvic acid is an intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. It improves coliform recovery when present in culture medium. It is involved in a metabolic regulatory pathway activated by mitochondrial oxidants. Pyruvate is involved in respiratory regulation in plants by interacting with alternative oxidase at a conserved cysteine residue. It may help prevent hydrogen peroxide mediated cell death.
Sodium pyruvate is utilized as a component in culture broth and media. Sodium pyruvate is used in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus. Sodium pyruvate has also been used to establish stably transfected human B cell lines.
Sodium Pyruvate has shown antioxidant properties and protective effects against oxygen radicals. Pyruvate is produced as part of glycolysis and is an intermediate in many metabolic pathways. It can be converted into acetyl CoA and enter the TCA Cycle.

Beschreibung: Agarose is a natural polysaccharide isolated from agar or agar-bearing marine algae. Its physical and chemical properties are particularly suited for use as a gel medium for diffusion and electrokinetic movement of biomolecules. Agarose is essentially biologically inert and forms relatively clear, transparent gels. Agarose based gels offer several advantages: High gel strength permits use of low concentrations. The macroporous nature of the gels allows rapid diffusion of high molecular weight molecules. Agarose is Non-toxic. Agarose gels are thermally reversible facilitating sample recovery. Staining and destaining may be done rapidly with minimal background. Because agarose forms macroporous gels that are electrically nonionic, it is an excellent medium for Isoelectric Focusing (IEF). A selection of different formulated agaroses with specific qualities for unique applications are available from MP.
Multipurpose Agarose is a versatile high gel strength agarose, especially designed for a wide range of molecular biology techniques. It is used for resolution of fragments over a large size range from 200 bp up to 50 kb by conventional electrophoresis. It is suitable for use in pulsed field gel electrophoresis and for blotting assays.
High gel strength agarose, especially designed for a wide range DNA. Versatile – separate fragments from 200 bp up to 50 kb by conventional electrophoresis. Concentrations between 0.4% and 6%. Multipurpose Agarose features the highest gel strength available, allowing 0.4 - 0.5% agarose gels. Significantly decreases electrophoresis times. Improves separation of very large fragments. Dissolves easily in a microwave.

Beschreibung: Below 35 to 40 °C gelatin swells and absorbs approximately 5 to 10 times its weight of water to form a gel. Gelatin is soluble in glycerol and acetic acid, and more soluble in hot than in cold water. It is practically insoluble in most organic solvents such as alcohol, chloroform, carbon disulphide, carbon tetrachloride, ether, benzene, acetone and oils. Sterile solutions of gelatin stored cold are stable indefinitely, but at elevated temperatures hydrolysis or rupture of peptide bonds occurs, increasing the number of free amino groups. Gel strength and viscosity gradually weaken upon prolonged heating in solution above ~40 °C; this degradation is accelerated by extremes in pH, proteolytic enzymes and bacterial action.
