Assay Principle
The Tribio® Ultra-sensitive Human IL-33 Fast ELISA is a solid phase ELISA designed to measure human IL-33 levels in cell culture supernatants, serum, and plasma. The main feature is that the kit uses our novel proprietary approaches to combine samples and detection into a one-step instead of the complicated traditional methods. It makes the assay simple, easy, accurate, and ultra-sensitive. The measurement can detect a concentration as low as 0.5pg/mL, and finish in 2 hours, with no need for 5-6 hours (Fig. 1). The detection range is from 0.5 to 2048 pg/mL. The levels of human IL-33 samples are parallel to the standard curves obtained using the kit standards linearly. Therefore, the kit can be used to determine relative mass values for natural human IL-33 protein.
The kit contains sufficient materials to run an ELISA on one 96-well plate.
Related Products Human IL-1ß ELISA (TBS3219)
Ultra-sensitive Human IL-33 ELISA Kit is a Solid-phase ELISA for the quantitative determination of Ultra-sensitive IL-33. The microplate is pre-coated with a capture antibody specific to the target. Target present in the sample or standard binds the immobilized antibody, is detected with a biotinylated detection antibody and streptavidin-HRP, and quantified colorimetrically against a standard curve.
Kit Components
The kit provides a pre-coated microplate, target standard for standard-curve generation, detection reagents (detection antibody and enzyme conjugate), wash buffer, substrate, and stop solution. Refer to the product datasheet for the complete component list and quantities.
