NCBI Description
This gene encodes the A-chain polypeptide of serum complement subcomponent C1q, which associates with C1r and C1s to yield the first component of the serum complement system. C1q deficiency is associated with lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains which include 6 A-chains, 6 B-chains, and 6 C-chains. Each chain contains an N-terminal collagen-like region and a C-terminal C1q globular domain. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Nov 2016]
Uniprot Description
C1QA iso2: 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.

Product Notes
The C1QA c1qa (Catalog #
AAA9418550) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The C1QA Antibody reacts with Human, Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's C1QA can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Western Blot: 1:1000-3000. Researchers should empirically determine the suitability of the C1QA c1qa for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.
It is sometimes possible for the material contained within the vial of
"C1QA, Polyclonal Antibody" to become dispersed throughout the inside of
the vial, particularly around the seal of said vial, during shipment and storage. We always
suggest centrifuging these vials
to consolidate all of the liquid away from the lid and to the bottom of the vial prior to
opening. Please be advised that
certain products may require dry ice for shipping and that, if this is the case, an
additional dry ice fee may also be
required.
