The present invention relates to a monoclonal antibody specific for N-myc downstream regulated gene 2 (NDRG 2) protein, a cell line producing the monoclonal antibody, a method for measuring a quantity and quality of NDRG 2 protein, and a protein chip using the same. In the present invention, NDRG 2, a cancer-related factor is specifically expressed in dendritic cells differentiated from a monocyte of human peripheral blood. Accordingly, the monoclonal antibody specific for the NDRG 2 protein, the protein chip comprising the same and the method for measuring a quantity and quality of the NDRG 2 protein by using the same can be applied to elucidate characteristics of the dendritic cell and perform a research on the NDRG 2. Therefore, the present invention may help clinically to investigate and treat intractable diseases and cancers using the dendritic cell.
