WebOct 1, 1977 · Phase separation temperatures, each corresponding to lower critical solution temperature ( LCST) for solutions of poly (ethylene glycol) (PEG) in water-sodium chloride (NaCl) and in water-propionic acid-sodium salt (Pro-Na), have been determined for PEG with molecular weights of Mη = 2.18 × 10 3, 8 × 10 3 and 719 × 10 3 over concentration ranges … WebSep 22, 2024 · A PEG 600/ammonium sulfate system was used to extract and separate lectin from Zihua snap-bean seeds. The purpose of the present work was to establish a method for selective separation of lectin directly from the crude extract of Zihua snap-bean seeds, based on an alternative method to fractionate the lectins.

WebMar 4, 2024 · The dextran-PEG system is one of the most famous systems exhibiting phase separation. Various phase behaviors, including the evaporation process of the dextran-PEG system, have been studied in order to understand the physicochemical mechanism of intracellular phase separation and the effect of condensation on the origin of life. WebOct 28, 2016 · The most common biphasic systems are formed by two polymers (usually polyethylene glycol (PEG) and dextran) or a polymer and a salt (e.g., phosphate, sulfate or citrate). Other types include, ionic liquids and short-chain alcohols [ 1, 2, 4, 6, 7, 10, 11 ]. WebJan 1, 2024 · Evidence is now mounting that liquid-liquid phase separation (LLPS) or condensation underlies the formation of membraneless bodies such as nucleoli in cells. The list of cell compartments thought to be formed via the process of LLPS is growing rapidly and touches a myriad of cell functions. unfinished picture frame moulding lengths
