Determination of polyethylene glycols by precipitation with iodine
Talanta, 1985Two methods for the determination of polyethylene glycols (PEGs) in aqueous solution by precipitation with iodine have been developed. For PEGs with molecular weight 4 x 10(3)-2 x 10(4) the excess of iodine is titrated with thiosulphate, and for PEGs with average m.w. > 2 x 10(4) turbidimetric measurement is used. Both methods are relatively simple and

Branched polyethylene glycol for protein precipitation
Biotechnology and Bioengineering, 2011AbstractThe use of linear PEGs for protein precipitation raises the issues of high viscosity and limited selectivity. This paper explores PEG branching as a way to alleviate the first problem, by using 3‐arm star as the model branched structure. 3‐arm star PEGs of 4,000 to 9,000 Da were synthesized and characterized.

Fractionation of dextrin by gradient polyethylene glycol precipitation
Journal of Chromatography A, 2016This work aimed at developing a novel approach, named gradient polyethylene glycol (PEG) precipitation, to fractionate dextrin into fractions with narrower molecular weight distribution. This approach was based on the incompatibility between PEG and dextrin in aqueous solution; this incompatibility is positively correlated with the molecular weight of ...

Purification of Apolipoprotein H by Polyethylene Glycol Precipitation
Protein Expression and Purification, 1996A new method of polyethylene glycol precipitation followed by heparin affinity chromatography was established to purify apolioprotein H (Apo H, beta 2-glycoprotein I). This method is simple and effective and yields more harvest of Apo H (3-4 mg Apo H from 100 ml fetal bovine serum) than the current HClO4 extraction method. There are notable differences

On the precipitation of proteins by polymers: The hemoglobin—polyethylene glycol system
Biopolymers, 1984AbstractThe addition of polyethylene glycol (PEG) of MW 6000 to solutions of oxy‐ and deoxyhemoglobins results in an increase in the thermodynamic activity of these proteins. This in turn results, when PEG concentration is high enough, in phase separation into two phases; a protein‐rich, PEG‐poor phase and a PEG‐rich, protein‐poor phase.

Background When screening for macroprolactin, many laboratories use precipitation by polyethylene glycol (PEG) with molecular weight 6000 (PEG6000) or 8000 (PEG8000), and report the percentage prolactin recovery.

Detection of Macroamylasemia Using Polyethylene Glycol Precipitation
Clinical LaboratoryThere are many factors that can cause elevated serum amylase levels, including pancreatic causes such as acute pancreatitis and chronic pancreatitis. Additionally, non-pancreatic causes, such as acute abdomen and acute parotitis, can also lead to increased serum amylase. These factors generally explain the consistency between elevated serum amylase and

Precipitation of proteins with polyethylene glycol: Characterization of albumin
Archives of Biochemistry and Biophysics, 1978Abstract The factors which govern the precipitation of albumin by the synthetic polymer, polyethylene glycol (PEG), have been investigated as part of a broader program to determine the molecular basis of the protein-precipitating action of synthetic polymers.
