Rat anti-C4b
C4d C4 Monoclonal Antibody | anti-C4 antibody
C4, Mouse, mAb 16D2
C4d
C4d
For unit size 0.5 mg or larger: PBS only (concentration< 0.5mg/ml)
IA: Plates were coated overnight with rat anti-murine C4 mAb 16D2 in carbonate buffer and blocked with 5% dry milk in PBS and 0.01% Tween 20.
IF: Spleens were snap frozen and stored at -80 degree C until cryosections were cute. (Section (5um) were fixed for 4 mins in ice-cold acetone. Sections were blocked with 2% BSA, 2% FCS and PBS. Biotinylated 16D2 was visualized using avidin-PE.
Application Use: For immunohistochemistry and Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.
C4 is an acute phase protein that is produced by hepatocytes, monocytes and intestinal epithelial cells and can be used- in experimental animals as a marker for activation of the classical complement pathway. Recent studies have demonstrated an association between graft rejection and C4d deposition in a mouse model for cardiac transplantation.

NCBI and Uniprot Product Information
Uniprot Description
C4B: C4 plays a central role in the activation of the classical pathway of the complement system. It is processed by activated C1 which removes from the alpha chain the C4a anaphylatoxin. The remaining alpha chain fragment C4b is the major activation product and is an essential subunit of the C3 convertase (C4b2a) and the C5 convertase (C3bC4b2a) enzymes of the classical complement pathway. Defects in C4B are a cause of susceptibility to systemic lupus erythematosus (SLE). A chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system. Interindividual copy- number variation (CNV) of complement component C4 and associated polymorphisms result in different susceptibilities to SLE. The risk of SLE susceptibility has been shown to be significantly increased among subjects with only two copies of total C4. A high copy number is a protective factor against SLE. Defects in C4B are the cause of complement component 4B deficiency (C4BD). A rare defect of the complement classical pathway associated with the development of autoimmune disorders, mainly systemic lupus with or without associated glomerulonephritis.

Product Notes
The C4 c4b (Catalog #AAA584166) is an Antibody produced from Rat and is intended for research purposes only. The product is available for immediate purchase. The C4, Mouse, mAb 16D2 reacts with C4b C4d and may cross-react with other species as described in the data sheet. AAA Biotech's C4 can be used in a range of immunoassay formats including, but not limited to, Immunoassay (IA), Immunofluorescence (IF), Immunoprecipitation (IP), Western Blot (WB). Application Notes: W: A non-reduced sample treatment and SDS-Page was used. The band size is 200x kDa (Ref.4). IA: Plates were coated overnight with rat anti-murine C4 mAb 16D2 in carbonate buffer and blocked with 5% dry milk in PBS and 0.01% Tween 20. IF: Spleens were snap frozen and stored at -80 degree C until cryosections were cute. (Section (5um) were fixed for 4 mins in ice-cold acetone. Sections were blocked with 2% BSA, 2% FCS and PBS. Biotinylated 16D2 was visualized using avidin-PE. Application Use: For immunohistochemistry and Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50. Researchers should empirically determine the suitability of the C4 c4b 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 "C4, Monoclonal 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.Precautions
