IHC image of C4d staining in human liver carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab87424, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

ICC image of ab87424 stained HepG2 cells. The cells were 100% Methanol fixed (5 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab87424, 5μg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM. This antibody also gave a positive result in 100% Methanol fixed (5 min) HeLa, and MCF-7 cells at 5μg/ml.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

C4d also known as the C4d complement is a degradation product of the complement component C4. It has a molecular weight of approximately 45 kDa. This protein is commonly expressed on the surfaces of endothelial cells in various tissues where it plays a role in the immune response. The presence of C4d on tissues is often detected using techniques like immunohistochemistry (IHC) also referred to as C4d IHC or C4d immunostain providing valuable insights into complement activation.
Biological function summary

The C4d protein acts as a marker for complement activation and is part of the larger complement cascade. C4d is primarily associated with the classical pathway and serves as an indicator of complement-mediated cell injury. The degradation of C4 into C4d is usually seen in immune responses where antibodies recognize antigens triggering sequence activation in the complement pathway. C4d's role as a marker facilitates the differentiation between antibody-mediated injury and other types of tissue damage.

Pathways

This complement protein gets involved in the classical pathway of the complement system which plays a critical role in innate and adaptive immunity. It is related to other proteins like C3 and C1q which are additional components within this pathway. These interactions are significant for the clearance of pathogens and also assist in enhancing the humoral immune response by promoting the deposition of complement on pathogenic surfaces.

C4d presence becomes particularly significant in conditions like transplant rejection and systemic lupus erythematosus (SLE). In transplant rejection its deposition on tissue samples might indicate antibody-mediated rejection where C4d binds to the tissue signaling an immune response against the transplanted organ. Additionally in SLE C4d's relation to other proteins such as C3 and C1q confirms its involvement in autoimmune responses where the immune system mistakenly targets the body's own tissues leading to chronic inflammation and damage.

ターゲットの情報

Precursor of non-enzymatic components of the classical, lectin and GZMK complement pathways, which consist in a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system.. Complement C4b-B. Non-enzymatic component of C3 and C5 convertases (By similarity). Generated following cleavage by complement proteases (C1S, MASP2 or GZMK, depending on the complement pathway), it covalently attaches to the surface of pathogens, where it acts as an opsonin that marks the surface of antigens for removal (By similarity). It then recruits the serine protease complement C2b to form the C3 and C5 convertases, which cleave and activate C3 and C5, respectively, the next components of the complement pathways (PubMed : 8538770). Complement C4b-B isotype catalyzes the transacylation of the thioester carbonyl group to form ester bonds with carbohydrate antigens, while C4b-A isotype is responsible for effective binding to form amide bonds with immune aggregates or protein antigens (PubMed : 8538770).. C4a anaphylatoxin. Putative humoral mediator released following cleavage by complement proteases (C1S, MASP2 or GZMK, depending on the complement pathway). While it is strongly similar to anaphylatoxins, its role is unclear. Was reported to act as a mediator of local inflammatory process; however these effects were probably due to contamination with C3a and/C5a anaphylatoxins in biological assays.
