Binary ethyleneimine structure

http://www.veterinaryworld.org/Vol.12/June-2024/4.pdf WebSep 1, 2004 · Binary ethyleneimine (BEI) is an aziridine compound, produced from bromoethylamine hydrobromide (BEA) commonly used for the inactivation of FMD virus during vaccine manufacturing. The validation of BEI, when used as an inactivant, is essential to ensure the quality of the inactivating agent and the validity of the process.

WebBeta-propiolactone (BPL), binary ethyleneimine (BEI) and chlorhexidine (CHX) were assessed. Treatment of virus-spiked human plasma with 0.025% BPL reduced virus infectivity titer to undetectable levels within 2 h, whereas BEI treatment (1 mM) showed a slower kinetic of inactivation, attaining a complete virus inactivation within 8 h of incubation. WebThe selective interaction between polyelectrolyte multilayers (PEM) consecutively adsorbed from poly(ethyleneimine) (PEI) and poly(acrylic acid) (PAC) and a binary mixture containing concanavalin A (COA) and lysozyme (LYZ) based on electrostatic interaction is reported.
