Biotin conjugated
WebConjugation involves reaction of a primary amine with an N-hydroxysulfosuccinimide ester linked to biotin. The oligonucleotide can be liberated from streptavidin agarose containing immobilized conjugate under mild conditions (neutral pH, 50 mM dithiothreitol). This cleavable conjugate is useful for affinity purification applications. WebBiotin molecules were then conjugated on the surface of MTX-HSA NPs. The anticancer efficacy of biotin targeted MTX-HSA NPs was evaluated in mice bearing 4T1 breast carcinoma.A single dose of biotin targeted MTX-HSA NPs showed stronger in vivo antitumor activity than non-targeted MTX-HSA NPs and free MTX.
