Background

Purified human complement component C3. The third component of complement is a centrally important constituent of both the alternative and classical pathways. Upon secretion, pro-C3 undergoes a site specific proteolytic cleavage to yield circulating C3, a protein containing two disulfide bonded subunits (Alpha 115 kD and Beta 75 kD). The concentration of C3 in serum is approximately 1.25 +/– 0.52 mg/mL.
