For reconstitution, we recommend adding 100 µL distilled water to a final antibody concentration of about 1 mg/mL. To use this carrier-free antibody for conjugation experiments, we strongly recommend performing another round of desalting. (Zeba Spin Desalting Columns, 7KMWCO, 0.5 mL, Product # 89882)
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). Plasma concentration is 35 µg/mL.
