Typical Testing Data/Standard Curve (for reference only)
Principle of the Assay: The Picokine™ Human PTX3 Pre-Coated ELISA (Enzyme-Linked Immunosorbent Assay) kit is a solid phase immunoassay specially designed to measure Human PTX3 with a 96-well strip plate that is pre-coated with antibody specific for PTX3. The detection antibody is a biotinylated antibody specific for PTX3. The capture antibody is monoclonal antibody from mouse, the detection antibody is polyclonal antibody from goat. The kit contains recombinant Human PTX3 with immunogen: Expression system for standard: NSO; Immunogen sequence: E18-S381. The kit is analytically validated with ready to use reagents. To measure Human PTX3, add standards and samples to the wells, then add the biotinylated detection antibody. Wash the wells with PBS or TBS buffer, and add Avidin-Biotin-Peroxidase Complex (ABC-HRP). Wash away the unbounded ABC-HRP with PBS or TBS buffer and add TMB. TMB is substrate to HRP and will be catalyzed to produce a blue color product, which changes into yellow after adding acidic stop solution. The density of the yellow product is linearly propotional to Human PTX3 in the sample. Read the density of the yellow product in each well using a plate reader, and benchmark the sample wells\' readings against the standard curve to determine the concentration of Human PTX3 in the sample.
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.
Samples: cell culture supernates, serum, plasma(EDTA) and saliva. Intra-assay Precision: Intra-Assay Precision (Precision within an assay): Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-assay Precision: Inter-Assay Precision (Precision accross assays):Three samples of known concentration were tested in separate assays to assess inter-assay precision.
