Description

A protein precipitant used to purify proteins

Polyethyleneimine is used for protein and nucleic acid precipitation, transfection assays, and to pretreat filters to increase the binding of proteins. Polyethyleneimine can also complex heavy metal ions. An effective permeabilizer of gram negative bacteria. Crosslinked polyethyleneimine is used as an enzyme carrier. Polyethyleneimine cellulose in small columns will separate cyclic nucleotides from related compounds at the same electrolyte concentration that is used for thin layer chromatography on Polyethyleneimine cellulose-coated plates. It is a water soluble polymer used as a membrane lubricant, useful in filtering frozen cell membranes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
