Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Plate: Pre-coated

Protocol: human PTX3 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for PTX3 has been precoated onto 96-well plates. Standards(NSO, E18-S381) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for PTX3 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human PTX3 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 20000pg/mL, 10000pg/mL, 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 312pg/mL human PTX3 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum, plasma(EDTA) or saliva to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each human PTX3 standard solution and each sample be measured in duplicate.

Assay Precision:

• Sample 1: n=16, Mean(ng/ml): 3.5, Standard deviation: 0.22, CV(%): 6.3
• Sample 2: n=16, Mean(ng/ml): 7.8, Standard deviation: 0.45, CV(%): 5.8
• Sample 3: n=16, Mean(ng/ml): 15.7, Standard deviation: 1.0, CV(%): 6.4,
• Sample 1: n=24, Mean(ng/ml): 3.86, Standard deviation: 0.28, CV(%): 7.3
• Sample 2: n=24, Mean(ng/ml): 8.1, Standard deviation: 0.48, CV(%): 5.9

Background:

Protein Function: Plays a role in the regulation of innate resistance to pathogens, inflammatory reactions, possibly clearance of self- components and female fertility. .

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.
