The invention relates to a method for obtaining TSH or TSH-free serum. The object is to develop a method for obtaining TSH, in particular human TSH and for eliminating TSH from serum or plasma, which are required as null matrices in immunoassays, which uses affinity chromatography specific ligand affine immunological reagents. The object is achieved by the use of monoclonal anti-TSH antibodies of medium affinity, which react specifically with an epitope of the b-chain of TSH, in particular by the use of the monoclonal antibody BL-TSH (b) 63. |
