The Human T-Box Protein 21 (TBX21) ELISA Kit (RD-TBX21-Hu) is an enzyme-linked immunosorbent assay for quantitative detection of TBX21 in Human samples. This kit uses the Traditional ELISA format for colorimetric detection of natural TBX21 in samples including cell lysates 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 TBX21 in samples. For research use only.
