This Complement C4c antibody is conjugated to Biotin
Application
Western Blotting (WB), Immunohistochemistry (IHC), ELISA
Specificity
It has been selected for its ability to recognize C4c in immunohistochemical staining and Western blotting.
Purification
Affinity Chromatography
Immunogen
Native Protein C4cC4b was cleaved by C3b inactivator (C3bINA) in the presence of C4b-binding protein and C4d and C4c isolated. The radioactive label and therefore the reactive thiol group were located to C4d. C4c was reduced and alkylated and the two alpha'-chain fragments of C4c were separated. The molecular weights, amino acid analyses and carbohydrate content of the three alpha'-chain fragments were determined. C4d has a mol.wt. of 44500 and a carbohydrate content of 6 % . The two alpha'-chain fragments of C4c have mol.wts. of 25000 and 12000 and carbohydrate contents of 10 and 22 % respectively. The antibody is a rabbit polyclonal antibody raised against C4c conjugated to biotin.

Sodium azide
Precaution of Use
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice
Avoid repeated freeze/thaw cycles
