Lysine biotinylation
Webshort peptides, however, the random biotinylation of the ε-amino groups of lysine residues is much more likely to block binding sites whose function is necessary for downstream applications of the biotinylated peptide. Labeling of lysine residues in peptides, especially short ones, may alter their functional properties and/or immunoreactivity. WebAbstract. We describe a procedure for lipopolysaccharide (LPS) biotinylation using N-biotinyl-L-lysine and application of the biotinylated LPS (Bi-LPS) to localization of LPS …
