Using Western blot analysis with a monoclonal antibody recognizing a 17-amino acid epitope of the 1,25-dihydroxyvitamin D3 [ 1,25(OH)2D3 ]receptor , we have detected two crossreacting proteins in activated normal human lymphocytes .
 protein: 1,25-dihydroxyvitamin D3 [ 1,25(OH)2D3 ]receptor; protein: monoclonal antibody; protein: 17-amino acid epitope; cell type: human lymphocytes; cell type: activated normal human lymphocytes; protein: crossreacting proteins
