Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to CD40L. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to CD40L. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain CD40L, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of CD40L in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Cytokine that acts as a ligand to CD40/TNFRSF5 (By similarity). Costimulates T-cell proliferation and cytokine production (By similarity). Its cross-linking on T-cells generates a costimulatory signal which enhances the production of IL4 and IL10 in conjunction with the TCR/CD3 ligation and CD28 costimulation (By similarity). Induces the activation of NF-kappa-B (By similarity). Induces the activation of kinases MAPK8 and PAK2 in T-cells (By similarity). Mediates B-cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL4 (By similarity). Involved in immunoglobulin class switching (By similarity).

Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level CD40L were tested 20 times on one plate, respectively.
|SENSITIVITY||The minimum detectable dose was 0.18ng/mL.|
|SPECIFICITY||This assay has high sensitivity and excellent specificity for the detection of CD40L.
No significant cross-reactivity or interference between CD40L and analogs was observed.
Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between CD40L and all analogs, therefore, cross reactivity may still exist.
