[Preparation and identification of monoclonal antibodies against human DcR3].

Aim: To prepare monoclonal antibodies(mAbs) against human DcR3 and identify their characterization.

Methods: BALB/c mice were immunized with purified His-DcR3 protein, and mAbs against DcR3 which prepared by hybridoma technique were purified and identified by their specificity, subtype, titers via ELISA and Western blot.

Results: Five hybridoma cell lines secreting mAbs against human DcR3 were obtained, which were determined as IgG1 subtype and ascites titers of five mAbs against DcR3 reached 1x10(-5)-1x10(-7).
