Recombinant Human Factor VIII Protein (rp217155) - SDS-PAGE 2 μg/lane of Recombinant Human Factor VIII Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 25.1 kDa under reducing conditions and 25.2 & 44.8 kDa under non-reducing conditions. Factor VIII, a non-covalent heterodimer comprised of a heavy chain (A1-A2-B domains) and light chain (A3-C1-C2 domains), circulates as an inactive procofactor in complex with von Willebrand factor (PMID: 16513527).
