Anti-Complement C3 alpha chain Antibody [7C1] (A85333)

Western blot analysis of Anti-a Subunit Of Complement Component 4 Antibody on human serum samples. Blot of 0.1 µg purified human C3 protein (Lane 1), 10 µg normal human serum proteins (Lane 2) was probed with Anti-a Subunit Of Complement Component 4 Antibody (1:5,000). The Anti-a Subunit Of Complement Component 4 Antibody binds strongly and cleanly to a band at about 115 kDa which represents the intact a subunit of C3 and various proteolytic bands at approximately 68 kDa and 48 kDa. Bands at 190 kDa and above are likely the pro-C3 and its glycosylated form.
