蛋白结构(Molecular Characterization)

PTX3 Structure

This protein carries a polyhistidine tag at the C-terminus

The protein has a calculated MW of 41.9 kDa. The protein migrates as 45-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

PTX3 SDS-PAGE

Mouse PTX3, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.

 

活性(Bioactivity)-ELISA

PTX3 ELISA

Immobilized Anti-PTX3 Antibody at 1 μg/mL (100 μL/well) can bind Mouse PTX3, His Tag (Cat. No. PT3-M52H6) with a linear range of 0.008-0.5 μg/mL (Routinely tested).

Protocol

 

背景(Background)

PTX3 is a prototypic long pentraxin consisting of a C-terminal 203-amino acid pentraxin-like domain coupled with an N-terminal 178-amino acid unrelated portion. Plays a role in the regulation of innate resistance to pathogens, inflammatory reactions, possibly clearance of self-components and female fertility. PTX3 can binds to C1q, but not C1s.
