The TribioTM Fast Human HE4 ELISA is designed to quantitatively detect Human HE4 levels in different tissues including skin, muscle, neural, serum, and other biological samples. The main feature is that the kit uses our novel proprietary approaches to combine samples and detections into a one-step instead of the complicated traditional methods. It makes the assay simple, easy, accurate and fast. The measurement can be finished in 3 hours, with no need for 4-5 hours (Fig. 1). The detection range is from 7 to 500 pg/mL. The levels of human HE4 samples are parallel to the standard curves obtained using the kit standards linearly. These results indicate that this kit can be used to determine relative mass values for natural human HE4 protein.
This standard curve(R2=0.9995) is provided for demonstration only. A standard curve should be generated for each set of samples assayed. Fig. 3 is an example of typical Data.
The minimum detectable dose (MOD) of human HE4 is typically 5 pg/ml.
The Intra-assay CV is 3.79%, the Inter-assay CV is ˂10%.
This assay recognizes natural and recombinant human HE4.
