Free Thyroxine (FT4) radioimmunoassay kit RIA
Diagnosis thyroid dysfunction
Precisely assess thyroid metabolism, even in the presence of changes in the binding proteins
Monitor drug therapy
- EXTENSIVE MEASUREMENT RANGE
- ACCURATE AND RELIABLE ASSAY
The principle of the assay is based on a two-step competition. First, the samples are incubated in coated tubes onto which anti-T4 polyclonal antibodies are adsorbed. A 125I-FT4 tracer is then added to saturate the remaining free antibody sites. Any unbound tracer is then removed.
Assay procedure: 30 min at RT / shaking + 60 min at RT / shaking.
Working range: 0.5 – 70 pg/mL (0.65-91 pmol/L)
Sample: serum – 100 µL
Analytical sensitivity: 0.5 pg/mL (0.65 pmol/L)
