Helical Organization of Blood Coagulation Factor VIII on Lipid Nanotubes
Published on: June 3, 2014
The interactions of human blood clotting Factor VIII:c with 2 monoclonal antibodies, C7F7 and BD10, were examined with an enzyme-linked immunosorbent assay (ELISA) method. A Scatchard-Sips plot approach to data analysis was used to calculate an average affinity (Ko), valence (n), and heterogeneity index (a) for each interaction. Using a Factor VIII:c coating ELISA method, the following constants were determined: BD10: Ko = 5.48 X 10(8) M-1; n = 0.31; a = 0.97; C7F7: Ko = 2.3 X 10(11) M-1; n = 0.018; a = 0.77.
