MBS825009 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the PTX3, ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing PTX3. The ELISA analytical biochemical technique of the MBS825009 kit is based on PTX3 antibody-PTX3 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect PTX3 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, PTX3. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Principle of the Assay: MBS Human PTX3 ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human PTX3 in Cell Culture Supernatants, Serum, Plasma. This assay employs an antibody specific for Human PTX3 coated on a 96-well plate. Standards and samples are pipetted into the wells and PTX3 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human PTX3 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of PTX3 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Background: PTX3 (Pentraxin 3) is a member of the pentraxin superfamily. This super family characterized by cyclic multimeric structure. The PTX3 gene is mapped to 3q25.32. The predicted 381-amino acid PTX3 protein has homology to the pentraxin protein family. Significant levels of PTX3 were detected in plasma of neutropenic patients with systemic A. PTX3 is effective in preventing CMV infection and reactivation, as well as subsequent Aspergillus infection. PTX3 activates the classical pathway of complementactivation and facilitates pathogen recognition by macrophages and DCs.
