ficolin

fi·co·lin

(fi'kō-lin),
A protein that structurally resembles mannose-binding lectin (MBL). The polypeptide chains have a N-terminal region, a collagenlike domain, and a globular region, which is fibrinogenlike. Although H-ficolin and L-ficolin are plasma proteins generated in the liver, M-ficolin is produced by monocytes, and is membrane bound. H- and L-ficolin can form oligomers and are capable of activating complement. M-ficolin may act as a phagocytic receptor on circulating monocytes for glycosylated proteins.
See also: L-ficolin, H-ficolin.

After blocking the endogenous peroxidase with 30 g/L hydrogen peroxide, for ficolin staining alone, sections were incubated in TBS with normal sheep serum, with either H-ficolin monoclonal antibody (clone 4H5) from HyCult Biotechnology or rabbit polyclonal anti-L-ficolin antibody (clone 2F5) from Tokai University.

The low circulating ficolin concentrations suggested an underlying mechanism of ficolins in preeclampsia.
To understand the role of ficolins in the underlying immune recognition in preeclampsia, we revealed high concentrations of H-ficolin and L-ficolin in placental lysate from established preeclamptic pregnancies (n = 5; Fig.
