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.

WebThe chemical formula for ethyleneimine is C 2 H 5 N, and its molecular weight is 43.07 g/mol. (7) Ethyleneimine occurs as a colorless, flammable, mobile liquid that is miscible … Binary ethylenimine (BEI) is a preparation of aziridine. It can be produced by heating bromoethylamine hydrobromide or 2-aminoethyl hydrogen sulfate in the presence of sodium hydroxide (Gabriel method). It contains at least one three-membered ring which is very reactive because of the ring strain. It … See more BEI is very hazardous since it attacks nucleic acids and proteins as described above. It can be neutralised by sodium thiosulfate; the thiosulfate is a nucleophile which opens the three-membered ring. The presence of … See more • Bahnemann, H. G. (1976).
