  • FunctionC1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system. The collagen-like regions of C1q interact with the Ca(2+)-dependent C1r(2)C1s(2) proenzyme complex, and efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or IgM antibody present in immune complexes.
  • Involvement in diseaseDefects in C1QA are a cause of complement component C1q deficiency (C1QD) [MIM:613652]. A rare defect resulting in C1 deficiency and impaired activation of the complement classical pathway. C1 deficiency generally leads to severe immune complex disease with features of systemic lupus erythematosus and glomerulonephritis.
  • Sequence similaritiesContains 1 C1q domain.
    Contains 1 collagen-like domain.
  • Post-translational
    modifications
    O-linked glycans consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups.
  • Cellular localizationSecreted.
  • Information by UniProt

Thank you for your reply.

I checked with the lab and we have not tested the protein for stability after reconstitution and would advise to immediately use the protein after reconstitution.

The buffer does not contain any protease in...

Thank you very much for your patience.

I can now confirm that we recommend to reconstitute lot GR116211-1 in 700ul ddH2O.

This will provide a concentration of ca. 1.43mg/ml.

I hope this information is helpful and wish you ...

Thank you for your patience, while I contacted the lab about the reconstitution volume.

The reconstitution volume before lyophilisation was 5.9mls. I am double checking with them, whether this is the actual volume they recommend to reconstitu...

Thank you for contacting Abcam yesterday.

I just wanted to let you know that I am still waiting to hear back from the lab about the volume to reconstitute the protein and as soon as I hear anything from them, I will forward it on.
