L-Thyroxine (T4) radioimmunoassay kit RIA
The T4-US kit is an immunoradiometric assay for a measure of the L-Thyroxine (T4).
For Research Use Only, not for use in diagnostic procedures.
- FAST ONE-STEP ASSAY
The principle of the assay is based on competition between 125-iodine radiolabeled T4 and the T4 contained in the samples for a fixed and limited number of anti-T4 polyclonal antibody binding sites adsorbed onto the tube walls.
One-step assay procedure: 45 minutes at RT / shaking.
Working range: 2.5 – 360 ng/mL (3.2-461 nmol/L)
Sample: serum or plasma – 20 µL
Analytical sensitivity: 2.5 ng/mL (3.2 nmol/L)
