Human Pentraxin 3, Long (PTX3) ELISA Kit

PTX3 (Pentraxin 3) is the prototype long pentraxin, an acute-phase glycoprotein induced by pro-inflammatory cytokines such as IL-1β and TNF-α and released by neutrophils, dendritic cells, endothelial cells, and fibroblasts during infection and tissue injury. This quantitative ELISA from Assay Genie is calibrated to measure human PTX3 across diverse sample matrices, with validated protocols for serum samples, plasma specimens, saliva, cell lysates, and tissue homogenates. The kit supports research into sepsis prognosis, cardiovascular risk stratification, autoimmune disease activity, and tumor microenvironment biology. The 96-assay microplate kit includes pre-coated wells, detection antibodies, recombinant standards, and chromogenic substrate; absorbance is read on a standard plate reader for concentration interpolation. Reconstituted reagents are kept on ice during use, and the kit is shipped refrigerated. Intended for research use only.
