Cu(I) stabilizing crosslinked polyethyleneimine.
Polyethyleneimine (PEI) is known for its metal-coordinating properties and in its crosslinked form has applications in different areas ranging from drug delivery to waste water treatment and recovery of trace metals. With the aim to regulate the coordination environment of Cu(I) and Cu(II) ions in marine coatings, we have prepared a triazole cross-linking agent with 'soft' coordination that can...
متن کاملLamellar architecture and crystalline transformation in supramolecular complexes of highly-branched polyethyleneimine-octadecanoic acid.
Supramolecular complexes of PEI(OA)x show a lamellar structure, and reversible crystal phase transition of the side alkyl chains in the complex can be observed by temperature-variable FT-IR spectroscopy.
متن کاملPolyethyleneimine is a potent systemic adjuvant for glycoprotein antigens.
Polyethyleneimine (PEI) is an organic polycation used extensively as a gene and DNA vaccine delivery reagent. Although the DNA targeting activity of PEI is well documented, its immune activating activity is not. We recently reported that PEI has robust mucosal adjuvanticity when administered intranasally with glycoprotein antigens. Here, we show that PEI has strong immune activating activity af...
متن کاملImmunostimulatory characteristics induced by linear polyethyleneimine-plasmid DNA complexes in cultured macrophages.
Intravenously injected plasmid DNA (pDNA) complexed with cationic liposome (lipoplexes) caused NF-kappaB-mediated cytokine production from macrophages, induced by CpG sequence in the pDNA. We have reported that cytokine production caused by linear polyethyleneimine (PEI)-pDNA complexes (PEI polyplexes) was much lower than that caused by lipoplexes (Kawakami, S., Ito, Y., Charoensit, P., Yamashi...
متن کاملPolyethyleneimine is an effective permeabilizer of gram-negative bacteria.
The effect of the polycation polyethyleneimine (PEI) on the permeability properties of the Gram-negative bacterial outer membrane was investigated using Escherichia coli, Pseudomonas aeruginosa and Salmonella typhimurium as target organisms. At concentrations of less than 20 micrograms ml-1, PEI increased the bacterial uptake of 1-N-phenylnaphthylamine, which is a hydrophobic probe whose quantu...
