Benefits
- ACCURATE AND RELIABLE ASSAY
Assay principle: competition
The principle of the assay is based on competition between anti-TSH receptor autoantibodies (TRAb) in the samples with the TSH receptor adsorbed onto the tube walls for binding sites on 125-iodine radiolabeled TSH.
Assay procedure: 2 h at RT / shaking + 60 min at RT / shaking.
