Cynomolgus TNF alpha kit
No-wash kit to quantify released Cynomolgus TNF alpha
Prostaglandin E2 (PGE2) is produced in multiple cell types from PGH2, a primary product of the arachidonic acid metabolism, via the prostaglandin synthase. PGE2 displays several biological functions, such as vasodilatation and smooth muscle relaxation, and is involved in pro- and anti-inflammation pathways. PGE2 production is a commonly used method for the detection of COX-1 and COX-2 modulation. The PGE2 kit is a highly sensitive method for quantifying PGE2, either in cell supernatant or directly in whole cells.
|Detection limit||10 pg/mL|
|Dynamic range||8 to 1000 pg/mL|
|Z'||0.9 for 20 µl assay volumes|
One benefit of the HTRF PGE2 assay is its ability to quantify PGE2 in the presence of cells without sacrificing assay performance. The results comparing direct cell-based versus supernatant transfer did not differ significantly. Monocytes were stimulated to produce PGE2 in the presence or absence of indomethacin, a known inhibitor of PGE2 production. The IC50 of indomethacin determined using HTRF technology (1.0 ± 0.4 nM) was in agreement with previously published data.
