Utilization of novel lectin-conjugated Au nanoparticles as Thomsen-Friedenreich onco-antigen target for in vitro cytotoxicity and apoptosis induction in leukemic cell line.

Leukemia is a tumor of blood-forming tissues including bone marrow and lymphatic nodes, which comprise biologically distinct subgroups. In the present study, Au NPs-PEG-Lectin was prepared as a drug targeting system for potential Thomsen-Friedenreich antigen (TF-Ag) presented on the surface of leukemic cells to induce cytotoxicity. Gold nanoparticles were prepared using citrate reduction method and conjugated with lectin via SH-PEG-COOH.
