PTX4 ELISA kits are immunoassay tools for the measurement of the protein pentraxin 4, which is encoded by the PTX4 gene in humans. The canonical protein structure is reported to have an amino acid sequence of 478 residues and a mass of 52.3 kDa. It is known to be secreted and is found to be widely expressed at low levels with highest levels in small intestine, testis and brain. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally glycosylated. Other alias names for this target include neuronal pentraxin-like protein C16orf38, pentraxin 4, long, and long pentraxin 4.
