With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter.

Synonyms : DNA/RNA/protein extraction reagent, DNA/RNA/protein isolation reagent, DNA/RNA/protein purification reagent, TRI Reagent® cell pellet solution, cell pellet RNA extraction, cell pellet RNA isolation, cell pellet RNA purification, single step RNA extraction reagent, single step RNA isolation reagent, single step RNA purification reagent, total RNA extraction solution, total RNA isolation solution, total RNA purification solution, TRI Reagent® RNA Isolation Reagent.

TRI reagent® is a quick and convenient ready-to-use reagent useful for efficient total RNA extraction or for the simultaneous isolation of RNA, DNA and protein. TRI reagent® is a mixture of guanidine thiocyanate and phenol in a monophasic solution.

Homogenization or lysis of the tissue sample in TRI reagent® dissolves RNA, DNA and protein. The addition of chloroform or 1-bromo-3-chloropropane followed by centrifugation results in the separation of the mixture into three phases: an aqueous phase containing the RNA, the interphase containing DNA, and an organic phase containing proteins. Each of the components can then be isolated after separating the phases.

General description

Tween^®20 is a polyoxyethylene sorbitol ester that belongs to the polysorbate family. It is a nonionic detergent having a molecular weight of 1,225 daltons, assuming 20 ethylene oxide units, 1 sorbitol, and 1 lauric acid as the primary fatty acid. The ethylene oxide subunits are responsible for the hydrophilic nature of the surfactant, while the hydrocarbon chains provide the hydrophobic environment. Sorbitol forms the backbone ring to which the ethylene oxide polymers are attached.

Application

TWEEN 20 is a non-ionic detergent that has been used in a variety of applications, including:

• Post-hybridization wash buffer after in situ hybridization.
• Used along with PBS (phosphate-buffered saline) as the washing buffer for ELISA and immunostaining.
• Acted as an emulsifying agent for the preparation of stable oil-in-water emulsions
• Used in pre-extraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins).
• Acted as a blocking agent for membrane-based immunoassays at a typical concentration of 0.05%.
• Used for lysing mammalian cells at a concentration of 0.005 to 0.5%.
