Type: Binding

Description: Recombinant Factor Xa was immobilized on a Biacore CM5 chip at 25 degrees C with a flow rate of 10 uL/min using amine coupling 10 mM NaPP, pH 7,4, according to Biacore standard protocol. Factor Xa was applied at a concentration of 10 ug/mL. Contact time between 6-10 min, depending on the stability of the protein.Kinetic titration experiments were performed at 25 degrees C with a flow rate of 30 uL/min, a sample contact time of 120 s and a dissociation time of 300 s in running buffer containing 2% DMSO. Solvent correction cycles (eight correction points, 1.4% - 2.8% DMSO) were run at the beginning, in the middle and the end of the successive series. For surface conditioning ten start-up cycles (buffer injections) were run. Data points were collected at a sample rate of 10 Hz. Data sets were processed and analyzed using the software Biacore 4000 Evaluation. Solvent corrected and double-referenced association and dissociation phase data were fitted to a simple 1:1 interaction model with mass transport limitations
