ターゲット情報

  • 機能C1q 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.
  • 関連疾患Defects 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.
  • 配列類似性Contains 1 C1q domain.
    Contains 1 collagen-like domain.

Anti-C1q antibody [7H8] 画像

  • ab11861 staining C1q (green) in human SHSY5Y cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 1% paraformaldehyde and blocked with 10% serum for 20 minutes at room temperature. Samples were incubated with primary antibody (1/50 in PBS) for 2 hours at 24°C. An undiluted Alexa Fluor®488-conjugated goat anti-rat IgG polyclonal was used as the secondary antibody. Counterstained with Hoechst 33258 (blue) for 10 minutes at room temperature.

I checked ab71940 and you are correct, it is a similar situation. Unless there is a specific note on the product datasheet stating it has low endotoxin levels, then antibodies are not prepared with endotoxin levels in mind and likely have high, albeit ...
