Product details

What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

For more information, read more on recombinant antibodies.

Conjugation ready
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Supplementary information

The C1QA protein is one part of the complement component 1q (C1q) molecule also called C1Q-A. This protein plays an important role in the immune system. The C1q complex consists of three polypeptide chains: C1QA C1QB and C1QC. C1QA alone has a mass of around 26 kDa. These proteins mainly express in immune cells like macrophages dendritic cells and B cells. It forms part of the extracellular matrix where it participates in immune functions.

Biological function summary

C1QA interacts with pathogens and modified host cells to trigger the complement cascade. This starts the activation of the classical pathway which enhances immune responses. C1QA together with C1QB and C1QC binds to Fc regions of antibodies attached to antigens. This binding leads to the subsequent activation of C1r and C1s proteases facilitating opsonization and clearance of immune complexes and apoptotic cells.

Pathways

The synthesis of C1QA plays an important role in the classical complement pathway and is part of the innate immunity. C1QA collaborates with proteins like C1QB and C1QC in this pathway. This pathway bridges innate and adaptive immunity by assisting in the removal of pathogens and cell debris. It also relates to the coagulation pathway where its activity can influence inflammation and tissue repair processes.

Impaired C1QA function links to conditions like systemic lupus erythematosus (SLE) and rheumatoid arthritis. These diseases often associate with inappropriate activation or regulation of the complement system. C1QA mutations or deficiencies can result in a higher susceptibility to SLE and interactions with C1QB and C1QC are also implicated in this disease. Moreover C1QA influences the pathogenesis of rheumatoid arthritis by modulating inflammation responses.

Target data

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.
