Following bioconjugation of these electrophilic linkers to the nucleophilic residue (cysteine or lysine) of a protein (step 1), the resulting TCO-decorated constructs can be subjected to a IEDDA reaction with tetrazines functionalized with fluorescent or near-infrared (NIR) tags (step 2). We successfully used this strategy to label bovine serum albumin with the TCO linker 8a and subsequently reacted it in a cell lysate with the fluorescein-isothiocyanate (FITC)-derived tetrazine 12. The same strategy was then used to label the bacte
