The SHENTEK® Human IL-6 ELISA Kit is intended for use in determining the presence of natural or recombinant human Interleukin-6 (hIL-6) in biological products, such as serum or cell culture supernatant.
This kit is based on the solid-phase enzyme-linked immunosorbent assay (ELISA) with a
double-antibody sandwich technique to determine the amount of hIL-6 in biological
products. A hIL-6-specific capture antibody was pre-coated into each well of microtiter
strips. Both Calibration Standards and test samples were simultaneously added to the
microtiter strips, and followed by incubation and washing. The biotinylated detection
antibody was added to the microtiter strips to bind the epitope of hIL-6, thus forming a
sandwich structure, which further reacted with streptavidin-labeled HRP (SA-HRP). TMB
substrate was added into reaction, catalyzed by enzymatic hydrolysis to produce a blue
colored product (maximum absorption peak at 655 nm). Finally, a stop solution was added
to terminate the enzymatic reaction, resulting in a yellow colored product (maximum
absorption peak at 450 nm). The absorbance values at 450 nm wavelength were positively
correlated with the hIL-6 concentration in the Calibration Standards and the samples. The
concentration of hIL-6 in the sample can be calculated using a dose-response curve.
