Human/Mouse Total COX-2 DuoSet IC ELISA Summary

Assay Type
Solid Phase Sandwich ELISA
96-well strip plate
Assay Length
4 hours 40 mins (after plate preparation)
Sample Volume Required
Cell lysates (100 µL)
Sufficient Materials
Kits available for two, five, or fifteen 96-well plates*
Please see the product datasheet

* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure total COX-2 in cell lysates. An immobilized capture antibody specific for COX-2 binds both phosphorylated and unphosphorylated COX-2. After washing away unbound material, a biotinylated detection antibody is used to detect both phosphorylated and unphosphorylated protein, utilizing a standard Streptavidin-HRP format.

Data Examples

Figure 1: The Human/Mouse Total COX-2 DuoSet IC ELISA specifically recognizes total COX-2, as shown by Western blot. Lysate prepared from CCD-1070Sk human foreskin fibroblasts treated with 5.0 ng/mL of recombinant human (rh) IL-1 beta (Catalog # 201-LB) for 16 hours was incubated in wells coated with Human/Mouse Total COX-2 Capture Antibody. Unbound material was removed by washing and bound material was solubilized in SDS gel sample buffer. The same lysate and the captured protein were electrophoresed, transferred to a PVDF membrane, and immunoblotted with an Anti-COX-2 Polyclonal Antibody (Catalog # AF4198). Only the band corresponding to human/mouse COX-2 was detected in captured material.

The amounts of COX-2 as quantified by the Human/Mouse Total COX-2 DuoSet IC ELISA are consistent with the relative amounts of COX-2 determined by qualitative Western blot analysis.

Figure 2: Quantification of induced COX-2. Human PBMCs, THP-1 human acute monocytic leukemia cells, and RAW 264.7 mouse monocyte/macrophage cells were cultured in the absence or presence of 100 nM Phorbol 12-myristate 13-acetate (PMA) for 48 hours and 1.0 µg/mL of Lipopolysaccharide (LPS) for an additional 24 hours. Human CCD-1070Sk cells were cultured in the absence or presence of 5.0 ng/mL of rhIL-1 beta for 16 hours. The lysates were quantified with this DuoSet IC ELISA. The same lysates were immunoblotted (inset) with an anti-COX-2 polyclonal antibody. The DuoSet IC ELISA results correlate well with the relative amounts of human/mouse COX-2 detected by Western blot.

Background: COX-2

Cyclooxygenase (COX), also known as prostaglandin G/H synthase, is a membrane bound enzyme partly responsible for the catalysis of prostanoid synthesis. COX is expressed as at least three different isoforms. COX-1 is constitutively expressed and thought to regulate a number of 'housekeeping' functions such as vascular hemostasis, renal blood flow, and glomerular function. COX-2 expression is tightly regulated and induced by inflammatory mediators such as growth factors, cytokines, and endotoxin. COX-3 appears to be much more strictly regulated spatially and is observed in greatest abundance in cerebral cortex.
