Percoll® is a medium for density gradient centrifugation of cells, viruses and subcellular particles. Percoll® is composed of colloidal silica coated with polyvinylpyrrolidone (PVP), which renders the material completely non-toxic and ideal for use with biological materials. Centrifugation…

N,N,N',N'-Tetramethylethylenediamin is a tertiary amine base. N,N,N',N'-Tetramethylethylenediamine is used to catalyze the formation of free radicals from ammonium persulfate or riboflavin. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel…

Isopropyl alcohol is widely used in chemistry, biochemistry and molecular biology. Industrial applications include its use in antifreezes, quick-drying oils, and quick-drying inks, and as a solvent for gums, shellac, and essential oils. Isopropyl alcohol has been utilized as a solvent in the…

Premixed liquid, 4X concentrate. Contains 250mM TRIS-HCl (pH6.8), 8% SDS, 40% glycerol, and 0.02% bromophenol blue. For protein sample preparation in the Laemmli SDS-PAGE system, without reducing the disulfide linkages.

n-Butanol is useful for the removal of ethidium bromide from DNA purified by CsCl gradient ultracentrifugation. It is also suitable for use in the concentration of dilute nucleic acid solutions by repeated extractions. Increased nucleic acid concentration improves recovery by ethanol precipitation.

Dimethyl sulfoxide (DMSO) is a highly polar aprotic organic reagent that has exceptional solvent properties for organic and inorganic chemicals. Dimethyl Sulfoxide is ideal for use as a cryoprotectant. Also used in chemical reactions, in polymerase chain reactions (PCR) as a PCR cosolvent to…

HFBA is a strong acid and an ion-pairing agent. The strong acidity of HFBA ensures that other acidic groups such as carboxylic acid moieties on biomolecules remain protonated, and thus the samples are able to interact with organic solvents in such processes as reverse phase chromatography. The…

Bovine Brain Extract (BBE) is made from fresh, unfrozen pituitary glands from young, healthy cattle less than 30 months old. They are born, raised and slaughtered in New Zealand from a USDA approved source. New Zealand cattle are internationally recognized for being free from bovine spongiform…

1,1,1,3,3,3-Hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties enabling it to dissolve substances that serve as hydrogen-bond acceptors. 1,1,1,3,3,3-Hexafluoro-2-propanol is a polar solvent of high ionizing power and facilitates Friedel–Crafts-type reactions, using…

Immuno-Fluore™ Mounting Medium is a mounting medium for immunofluorescence preparations. A stabilizing agent has been added that inhibits the fading of fluorescence under the influence of ultraviolet light.

Ammonium sulfide solution (aqueous ammonium sulfide) is a 20% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has…

Bovine Pituitary Extract (BPE) is made from fresh, flash-frozen pituitary glands from young, healthy cattle between the ages of 18-22 months. The cattle are born, raised and slaughtered in New Zealand from a USDA approved source. New Zealand cattle are internationally recognized as free from bovine…

Lipoprotein- cholesterol is a mixture of lipoprotein cholesterol, phospholipids and fatty acids. For use as a serum-free or serum-reduced media nutrient supplement, calibration of cholesterol values, and enzymatic or non-enzymatic cholesterol determinations.

Chlorhexidine digluconate, a bis(biguanide) family cationic broad spectrum antibiotic is an antiseptic and disinfectant agent. It is effective against a wide range of bacteria, some fungi and some viruses, and an agent for the prevention of gingivitis. Chlorhexidine digluconate solution inhibits…

Albumin, bovine path 5 can be used as a medium in density gradient centrifugation or as an addition to tissue culture growth medium. Also used as an additive to cell culture media, especially serum-free media. It provides a range of benefits including protection from oxidative damage and…

N,N,N',N'-Tetramethylethylenediamine is used to catalyze the formation of free radicals from ammonium persulfate or riboflavin. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for sieving macromolecules such as nucleic acids…
