Product details:
Human Pentraxin 3 / PTX3 ELISA Kit (ab214570) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Pentraxin 3 / PTX3 protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, tissue extracts, and saliva. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Pentraxin 3 / PTX3 with 3.4 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Pentraxin 3 (also known as pentraxin-related protein PTX3 or TSG-14) is a secreted protein with a role in innate immune response. It is secreted by many cell types during infectious situations. The standard protein provided in this kit corresponds to the C-terminal Pentaxin domain of Pentraxin 3.

Pentraxin 3 (PTX3) also known as TSG-14 or TNF-Inducible Gene 14 Protein is an important component of the immune system. Mechanically PTX3 functions as part of the body's defense mechanism against pathogens and tissue damage. It has a molecular weight of approximately 42 kDa and is expressed in a range of tissues such as the immune cells endothelium and epithelial cells. Upon inflammatory signals these cells secrete PTX3 which quickly identifies microbial molecules and apoptotic cells.
Biological function summary
The role of PTX3 extends beyond simple pathogen recognition. It is involved in the regulation of inflammation and tissue homeostasis. As part of the pentraxin superfamily PTX3 plays a role in the formation of complexes with other molecules such as complement components. These interactions modulate the complement cascade an essential part of the innate immune response and influence the resolution of inflammation. PTX3 also interacts with extracellular matrix components stabilizing tissue structure during immune response.
Pathways
PTX3 integrates into vital immune signaling networks. It actively participates in the complement pathway where it regulates the activity of C1q and C3 key complement proteins. Additionally PTX3 connects with the Toll-like receptor (TLR) signaling pathway. This interaction helps modulate the body's response to microbial infections by influencing the activity of TLR4 among other related proteins which are fundamental in recognizing pathogen-associated molecular patterns.
PTX3 is linked to various inflammatory conditions. High levels of PTX3 often indicate a response to cardiovascular diseases such as atherosclerosis. In this context its interactions with C1q highlight its role in modulating disease progression. PTX3 also relates to autoimmune diseases like rheumatoid arthritis where its increased expression correlates with disease severity. In rheumatoid arthritis PTX3 can interact with pro-inflammatory cytokines like TNF-alpha exacerbating the inflammatory process.
