Applications
Our Abpromise guarantee covers the use of ab76425 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| ICC | 1/100 - 1/250. | |
| WB | 1/500 - 1/1000. Detects a band of approximately 26 kDa (predicted molecular weight: 26 kDa). | |
| Flow Cyt | 1/50. ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody. |
|
| IHC-P | 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. Use of HRP-conjugated or polymerized HRP secondary antibodies, stronger signals have been found using the polymerized HRP secondary. |
Target
-
FunctionC1q 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.
-
Involvement in diseaseDefects in C1QA are the cause of complement component C1qA deficiency (C1QAD) [MIM:120550]. 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.
