Factor I, a serine protease, is a regulatory component of both the alternative and the classical complement pathway. Factor I is synthesized as a single chain precursor of 88 kDa, processed to yield the active form, composed of two disulfide-linked chains, the a-chain (50 kDa) and the b-chain (38 kDa) (2). Plasma concentration is 35 µg/ml (1).
Factor I isolated from human plasma
HYB 061-02 is specific for the a-chain of human factor I
Not determined
HYB 061-02 reacts strongly with factor I. Strong reaction is seen with normal human plasma, and no reaction is seen with plasma from patients deficient in factor I, when tested in sandwich ELISA in combination with a polyclonal antibody against factor I (eg. sheep anti human factor I from Serotec). In Western blotting after SDS-PAGE, HYB 061-02 reacts with factor I in non-reduced form.
