Plasmid DNA partitioning and separation using poly(ethylene glycol)/poly(acrylate)/salt aqueous two-phase systems
(Elsevier B.V., 2012-04-13)
Phase diagrams of poly(ethylene glycol)/polyacrylate/Na2SO4 systems have been investigated with respect to polymer size and pH. Plasmid DNA from Escherichia coil can depending on pH and polymer molecular weight be directed ...
Antimicrobial effect of intracanal substances
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2007-09-01)
In some situations, endodontic infections do not respond to therapeutic protocol. In these cases, it is suggested the administration of an alternative intracanal medication that presents a wide spectrum of action and has ...
AGAROSE-GEL IMMUNODIFFUSION TESTS WITH the ADDITION of PEG (POLYETHYLENE-GLYCOL 6000) for the DIAGNOSIS and SEROLOGICAL FOLLOW-UP of PARACOCCIDIOIDOMYCOSIS INFECTION
(Kluwer Academic Publ, 1993-09-01)
By using PEG (polyethylen glycol 6000) in the gel immunodiffusion tests (ID), the precipitin lines were increased in 25.5% of the 192 sera reactions and the titers were increased from one to four serial dilutions in 44.6% ...
Effect of surfactants and polyethylene glycol on the activity and stability of a lipase from oilseeds of Pachira aquatica
(Springer, 2008-08-01)
Lipases from oilseeds have a great potential for commercial exploration as industrial enzymes. Lipases are used mixed with surfactants in cleaning and other formulated products, and accordingly, both components must be ...
Phase Diagrams of the Aqueous Two-Phase Systems of Poly(ethylene glycol)/Sodium Polyacrylate/Salts
(Mdpi Ag, 2011-03-01)
Aqueous two-phase systems consisting of polyethylene glycol (PEG), sodium polyacrylate (NaPAA), and a salt have been studied. The effects of the polymer size, salt type (NaCl, Na2SO4, sodium adipate and sodium azelate) and ...
Protein partitioning in poly(ethylene glycol)/sodium polyacrylate aqueous two-phase systems
(Elsevier B.V., 2008-01-12)
The partition of hemoglobin, lysozyme and glucose-6-phospate dehydrogenase (G6PDH) in a novel inexpensive aqueous two-phase system (ATPS) composed by poly(ethylene glycol) (PEG) and sodium polyacrylate (NaPA) has been ...
Potential tuberculostatic agents: Micelle-forming copolymer poly(ethylene glycol)-poly(aspartic acid) prodrug with isoniazid
(Wiley-Blackwell, 2001-06-01)
With the objective of obtaining slow-acting isoniazid derivatives, of potential use as chemoprophylactics or chemotherapeutics in tuberculosis, the micelle-forming copolymer of poly(ethylene glycol)-poly(aspartic acid) ...
Dynamic viscosity of binary and ternary mixtures containing poly(ethylene glycol), potassium phosphate, and water
(Amer Chemical Soc, 2004-09-01)
Dynamic viscosity of binary mixtures of poly(ethylene glycol) molar mass 1500 da + water, potassium phosphate + water, and ternary mixtures of poly(ethylene glycol) molar mass 1500 da + potassium phosphate + water were ...
Fermentative characteristics and aerobic stability of sorghum silages containing different tannin levels
(Elsevier B.V., 2009-10-28)
Two experiments were conducted to evaluate effects of tannin levels in sorghum silages Supplemented, or not, with polyethylene glycol (PEG) on silage chemical composition and fermentative characteristics as well as aerobic ...
Synthesis, characterization and solution properties of amphiphilic N-isopropylacrylamide-poly(ethylene glycol)-dodecyl methacrylate thermosensitive polymers
(Elsevier B.V., 2005-07-15)
Terpolymers of N-isopropylacrylamide, dodecyl methacrylate (DOMA) and poly(ethylene glycol) (PEG) methacrylate, were synthesized by random copolymerization, and the composition was controlled to achieve systems having ...
