Tweens® are a series of nonionic surfactants derived from sorbitan esters. They are soluble or dispersible in water but differ widely in organic and oil solubilities. Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.
Tween® 80 has been widely used in biochemical applications including: solubilizing proteins, isolating nuclei from cells in culture selective protein extraction growing of tubercule bacilli, and emulsifying and dispersing substances in medicinal and food products. It has little or no activity as an anti-bacterial agent. It has been shown to have an adverse effect on the antibacterial effect of methyl paraben and related compounds. Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines.
Soluble/miscible in water to give a clear yellow solution; miscible with alcohol, dioxane, and ethyl acetate; practically insoluble in liquid paraffin and fixed oils (such as mineral oil).
Autoclaving of solutions is not recommended. Sterile filtering is suggested with a 0.22 micron filter. Tween® may need to be warmed to about 40 °C and alternated with portions of hot distilled water while being poured through the filter.
Store at Room Temperature (15-30 °C).

Betaine is a quaternary amine found in bacteria and higher plants which acts as an osmoprotectant (able to restore and maintain osmotic balance in living cells) and enhances the freezing tolerance of of living organisms. This is probably due to its involvement in the protection of macrocomponents of plant cells, such as protein complexes and membranes, under stress conditions. Betaine is biosynthesized in living cells by a two-step oxidation method from choline. The primary enzyme involved in this biosynthesis is choline oxidase.

β-NADP is a coenzyme necessary for the alcoholic fermentation of glucose and the oxidative dehydrogenation of other substances. It occurs widely in living tissue, especially in the liver. Nicotinic acid can be converted to nicotinamide in the body and, in this form, is found as a component of two oxidation-reduction coenzymes: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). The nicotinamide portion of the coenzyme transfers hydrogens by alternating between oxidized quaternary nitrogen and a reduced tertiary nitrogen. NADP is an essential coenzyme for glucose-6-phosphate dehydrogenase which catalyzes the oxidation of glucose-6-phosphate to 6-phosphogluconic acid. This reaction initiates metabolism of glucose by a pathway other than the citric acid cycle. This route is known as the hexose phosphate shunt or phosphogluconate pathway. Other enzymes which utilize NADP as a coenzyme are: Alcohol dehydrogenase:NADP dependent; Aromatic ADH:NADP dependent; Ferredoxin-NADP reductase; L-Fucose dehydrogenase; Gabase; Galactose-1-phosphate uridyl transferase; Glucose dehydrogenase; L-Glutamic dehydrogenase; Glycerol dehydrogenase:NADP specific; Isocitric dehydrogenase; Malic enzymes; 5,10-Methylenetetrahydrofolate dehydrogenase; 6-Phosphogluconate dehydrogenase and Succinic semialdehyde dehydrogenase.

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatized biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4.5 - 5 and requires just minutes to complete.
