Mouse anti Human C4c antibody, clone 033D-69.4.1 (10-12) recognizes complement component 4c (C4c). The complement 1 complex cleaves complement 4 (C4) to form C4b and C4a. C4b levels are strictly regulated. Single site cleavage of the C4b’s alpha chain by Factor I forms iC4b and blocks C3 convertase, inhibiting opsonisation and activation of the classical pathway. iC4b is further degraded into the inactive fragments C4d and C4c. C4c consists of two a-chain fragments, alpha 4 (13 kDa) and alpha 3 (25 kDa) linked to a beta chain through disulphide bridges and a gamma chain. It is expressed in the blood plasma.

Applications of C4c antibody
|Immunohistology - Frozen
- 1Clone 10-12 binds both C4c and C4 and so is not suitable for all ELISA applications.
Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
- For best results Bio-Rad recommend HISTAR detection kits.
- Histology Positive Control Tissue
- Kidney sections from post-streptococcal glomerulonephritis patients.
