Abstract
The present invention relates to methods for detecting Ficolin-3 dependent activation of the lectin pathway of complement, methods for identifying abnormalities in Ficolin-3, and methods for screening for deficiencies/and or identifying abnormalities in any downstream components of the Ficolin-3 dependent activation of the lectin pathway of 5 complement using an acetylated Ficolin-3 ligand, said methods generally comprising the steps of: (a) providing a sample of blood, serum, plasma, another body fluid or an extract thereof; (b) (optionally) preventing in the sample activation of the classical pathway and/or the alternative pathway and/or any non-Ficolin-3 mediated activation of the lectin pathway; (c) acetylating a molecule; (d) contacting said acetylated molecule 10 with said sample, in conditions that permit specific binding of Ficolin-3 to said acetylated molecule, and, (e) detecting and quantifying specific binding of the Ficolin-3 to said acetylated molecule, (f) determining in the sample complement activation and/or deposition by the detection of a C2, C3, C4 and/or a C5 cleavage product and/or by detecting any of the terminal complement complex components C6, C7, C8 or C9 …
