Introduction | PTX3 is part of the pentraxin family sharing the C-terminal domain with short pentraxins and containing a unique N-terminal domain. PTX3 is produced and released at inflammatory sites by various cell types including monocytes/macrophages, endothelial cells, vascular smooth muscle cells, fibroblasts, and adipocytes. PTX3 is involved in the regulation of innate resistance to pathogens, inflammatory reactions, possibly clearance of self-components and female fertility. PTX3 is used as a marker for disease activity of psoriasis. High serum PTX3 levels are associated with the disease severity of systemic sclerosis. Elevated serum PTX3 is associated with pulmonary fungal infections. |
Description | Recombinant Human PTX3 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 401 amino acids (18-381 a.a) and having a molecular mass of 44.4 kDa.
PTX3 is fused to a 36 amino acid His Tag at N-terminus and purified by proprietary chromatographic techniques. |
Source | Escherichia Coli. |
Physical Appearance | Sterile filtered colorless solution. |
Formulation | The PTX3 protein contains 20mM Tris-HCl buffer pH-8.5, 1mM DTT and 10% glycerol. |
Stability | Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles. |
Purity | Greater than 90% as determined by Analysis by SDS-PAGE. |
