ABSTRACT
Aim To study targeting capability of anti-CD19 (Fab)-LDMto CD19 +B lymphoma cells in vi-vo and in vitro.Methods Flow cytometry was em-ployed to determine the affinity of Cy5 labeled anti-CD19 (Fab)-LDP to human lymphoma Raji cells.And the optical imaging system was used to analyze the dis-tribution of Cy5-anti-CD19 (Fab )-LDP in lymphoma-transplanted xenograft nude mice in vivo.Results The results of flow cytometry demonstrated that Cy5-an-ti-CD19(Fab)-LDP had remarkable affinity with lym-phoma Raji cells;Raji lymphoma xenograft model was established successfully in nude mice and in vivo fluo-rescence imaging analysis indicated that the antibody-drug conjugates could specially be localized in the tar-get tumor.Conclusion The experiments in vivo and vitro confirm that anti-CD19 (Fab)-LDP has remarka-ble affinity to targeting CD19 +lymphoma cells,and the antibody drugs anti-CD19 (Fab )-LDP have the probability to be new drugs for the treatment of malig-nant lymphoma.
