A monoclonal antibody produced against Naked2

Monoclon Antib Immunodiagn Immunother. 2013 Aug;32(4):290-4. doi: 10.1089/mab.2012.0111.

Abstract

Naked2 (NKD2) is a member of the Naked family and negatively regulates canonical Wnt signaling. NKD2 may play a role in embryo development and tumor formation by affecting Wnt signaling. In the present study, we describe the establishment of a monoclonal antibody against NKD2 (anti-NKD2 MAb) through the hybridoma method. The purified anti-NKD2 MAb measured a titer of 2.56 × 10(5) against NKD2 by indirect ELISA. Western blot analysis, immunoprecipitation, and confocal microscope showed that the anti-NKD2 MAb can specifically combine NKD2 protein in SW480 and LOVO cells. Competitive inhibition assays of Western blot and indirect ELISA showed that the anti-NKD2 MAb can be blocked with NKD2(1-217) protein. The anti-NKD2 MAb would be helpful for further studies on the structure activity relationship, protein detecting, and cell-signaling pathway of NKD2.
