Web22 oct. 2013 · In nature, transglutaminases catalyze the formation of amide bonds between proteins to form insoluble protein aggregates. This specific function has long been exploited in the food and textile industries as a protein cross-linking agent to alter the texture of meat, wool, and leather. In recent years, biotechnological applications of transglutaminases … WebThe current study has therefore characterized the effect on dendrimer disposition of conjugating α-carboxyl protected methotrexate (MTX) to a series of PEGylated 3H-labeled poly-l-lysine dendrimers ranging in size from generation 3 (G3) to 5 (G5) in rats. Dendrimers contained 50% surface PEG and 50% surface MTX.

WebTo prepare PEGylated sCT resistant to the proteolytic degradation, the lysine residues susceptible to tryptic activity were selectively PEGylated by controlling reaction pH. The PEGylated sCT showed strong resistance against enzymatic degradation in rat nasal mucosa, with 56-fold prolonged half-life compared with that of native sCT. computer security and virusThe first step of the PEGylation is the suitable functionalization of the PEG polymer at one or both ends. PEGs that are activated at each end with the same reactive moiety are known as "homobifunctional", whereas if the functional groups present are different, then the PEG derivative is referred as "heterobifunctional" or "heterofunctional". The chemically active or activated derivatives of the PEG polymer are prepared to attach the PEG to the desired molecule. computer security art and science 2nd editionWebSurface engineering masks the cationic charge of dendrimer surface either by neutralization of charge, for example PEGylation, acetylation, carbohydrate and peptide conjugation; or by introducing negative charge such as half generation dendrimers. ecolife kitchenWebPEGylation is considered one of the most successful techniques to enhance the therapeutic and biotechnological potential of peptides and proteins. 1. ...
