• Clonality: Polyclonal
• Specificity: Human complement C1q
• Form/Format: Supplied as delipidated, defibrinated and 0.2 um filtered in 0.2M Tris, pH 7.4, with 0.5M NaCl and 0.1% NaN3.
• Concentration: Molar F/P ratio: 3.43. (varies by lot)
• Sequence Length: 245

• Applicable Applications for anti-C1QC antibody: User optimized
• Biological Significance: Complement C1q is part of the C1 complex and this complex is the first complement component in the cascade referred to as the classical pathway of complement. C1 is actually a non-covalent assembly of three different proteins (C1q, C1r, and C1s) bound together in a calcium-dependent complex. C1q has six extended arms with domains at the end of each arm that bind to the Fc domains of immunoglobulins.
• Cross-Reactivity: Monoprecipitin arc versus normal human plasma and 2x concentrated normal human serum.
• Tag/Conjugate: FITC
• Immunogen: Complement C1q antibody was raised in goat using human complement C1q as the immunogen.
• Preparation and Storage: Store at 4 degree C for short term storage. Aliquot and store at -20 degree C for long term storage. Avoid repeated freeze/thaw cycles.

NCBI Description

This gene encodes a major constituent of the human complement subcomponent C1q. C1q associates with C1r and C1s in order to yield the first component of the serum complement system. A deficiency in C1q has been associated with lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains, and six C-chains. Each chain contains a collagen-like region located near the N-terminus, and a C-terminal globular region. The A-, B-, and C-chains are arranged in the order A-C-B on chromosome 1. This gene encodes the C-chain polypeptide of human complement subcomponent C1q. Alternatively spliced transcript variants that encode the same protein have been found for this gene.

Uniprot Description

C1QC: 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. Defects in C1QC are a cause of complement component C1q deficiency (C1QD). 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.
