Rabbit anti Human C1 esterase inhibitor Antibody

Precipitating polyclonal rabbit antiserum to human C1 esterase inhibitor. C1 esterase inhibitor is a single chain acid glycoprotein with a molecular weight of 110,000. The protein has a high carbohydrate content. In immunoelectrophoresis it ha an alpha mobility. The concentration in normal serum ranges from 150 to 350 mg/ml. Reduced levels are observed in hereditary angioedema.
