“…Although there are several amine reactive biotinylation reagents available from commercial sources, a new biotinylation reagent was designed and synthesized for biotinylation of SBDs. One reason for synthesizing the new biotinylation reagent was that commercially available biotinylation reagents, such as the N-hydroxysuccinimidyl (NHS) ester of biotin, 26 (Table 4) (40), or the NHS ester of aminocaproate linked biotin, 27 (41), could be degraded by the action of the serum enzyme biotinidase (42)(43)(44)(45). Another consideration was the fact that most commercially available biotinylation reagents have low water solubility, 5 making their use questionable for the preparation of compounds containing multiple biotin moieties.…”

“…Unfortunately, our (unreported) studies of the localization of radiolabeled biotin molecules have not provided a clear answer to the question of kidney binding of radiolabeled biotin. The results obtained have been complicated by the issue of biotinidase cleavage (22)(23)(24)(25) of the biotin derivatives used, by issues relating to endogenous biotin (26), and by the fact that renal clearance is the normal route of excretion of the radiolabeled biotin derivatives. This issue cannot be readily resolved from literature reports either, as many other investigators have not addressed it directly or have not provided data that could be used to assess the localization quantitatively.…”
