Background: Pentraxin 3/TSG-14
Pentraxin 3 (PTX3), also known as TNF-stimulated gene 14 (TSG-14), is a secreted glycoprotein belonging to the Pentraxin family of proteins. It is the prototypical long Pentraxin, exhibiting a C-terminal Pentraxin domain characteristic of the family, and a unique N-terminal domain. It is produced by several cell types including endothelial and mononuclear cells. PTX3 acts as a pattern recognition receptor with non-redundant roles in the innate immune response to several microbial agents including the fungal pathogen Aspergillus fumigatus. Overexpression leads to enhanced pro-inflammatory responses. PTX3 is induced in response to LPS and inflammatory cytokines including TNF-alpha and IL-1 beta.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 50 µL of Assay Diluent to each well.
- Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
- Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.
- Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
- Aspirate and wash 5 times.
- Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
