title: A simple method for the detection and assay of C1.
abstract: A simple method is described for the production of human serum deficient in the complement component C1. This C1-deficient serum can be used for the assay of C1. If the amount of C1 is expressed in terms of its subcomponent C1q, the method can detect C1 when the C1q subcomponent content is only 10 pg.
