The set was composed to cover a wide range of detergents proposed earlier for solubilization of membrane-bound proteins and it included various non-ionic, ionic, as well as zwitterionic
Reagents for zwitterionic
buffers came from Boehringer and Serva.
Linear and branched zwitterionic
derivatives of polyethyleneimine as carriers for pharmacologically active components, Macromolecules Chemistry, Pharmacologically active polymers, 184, 793 (1983).
The composition excludes anionic, amphoteric and zwitterionic
g] differences were observed when terminal groups of some end-functionalized block copolymers of styrene and isoprene were substituted by zwitterionic
Evaluation of nonionic and zwitterionic
detergents as membrane protein solubilizers in two-dimensional electrophoresis.
Cationic, anionic, and zwitterionic
surfactants are charged species and obviously can only be used in formulations where the charge can be tolerated.
rhodium complexes were shown to be excellent catalysts for the hydroformylation of a wide range of olefins including polybutadiene to the corresponding aldehydes.
When dissolved in water, the solution is mainly composed of the zwitterionic
species, together with a smaller amount of the cationic and anionic species.
A peak around 2800cm-1 is assigned to the zwitterionic
linkage produced by hydrogen bond formation in HC=N- group.
The composition is comprised of a chelant selected from the group consisting of glutamic acid, diethylenetriamine penta methylphosphonic acid; diethylenetriamine pentaacetic acid, methyl glycinediacetic acid and mixtures thereof; a surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic
, semi-polar nonionic surfactants and mixtures thereof; a branched nonionic surfactant; and aqueous liquid carrier.
