The General Thyroxine (T4) ELISA Kit (RDR-T4-Ge) is an enzyme-linked immunosorbent assay for quantitative detection of T4 in General samples. This kit uses the Ready to Use ELISA format for colorimetric detection of natural T4 in samples including serum, plasma and other biological fluids. The kit is easy to use and comes with a pre-coated microplate and all necessary reagents and buffers. The standard curve generated in the experiment is used to calculate the concentration of T4 in samples. For research use only.
