T-cell surface glycoprotein CD4 (CD4)

Links to databases

 

CD4 is a glycoprotein found on the surface of immune cells such as T helper cells, functioning as an accessory protein for MHC class-II antigen/T-cell receptor interactions. It is involved in T-cell activation.

Analytical Measuring Range

Please note: the technical data reported below refers to the measured value in the in vitro validation assays. The calibrator curve below shows the performance of the assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens. Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please visit our FAQ page (https://www.olink.com/question/what-is-npx).

Precision

Within run precision Coefficient of Variation (CV)
10%
Between run precision Coefficient of Variation (CV)
9%

Precision (repeatability) is calculated from linearized NPX values over LOD.
