Sheep anti Human C1q antibody recognizes human C1q, a sub-component of complement C1. C1q associates with complement components C1r and C1s, which are required for the progression of the proteolytic complement cascade. Deficiency of C1q has been associated with lupus erythematosus and glomerulonephritis (Troedson et al. 2013).

Sheep anti human C1q antibody may cross react with C1q in other species.
