Blood Coagulation Factor Ix: Purification, Activation, Crystallization, Juliet Mcgill

WWU Honors College Senior Projects

This paper presents readers with an optimized procedure for the purification, activation, and crystallization of selected blood coagulation Factor IX double mutant (FIX_2). Through the completion of this work, we aim to enhance future biochemical and structural studies by providing an easier means for the FIX_2 production, in order to increase understanding of the protein’s function within the blood coagulation cascade. The initiation of the blood coagulation cascade is brought on by activation of inactive Factor VIII (FVIII) protein though contact with tissue factor, the FVIII protein then binds to an activated platelet surface where it must wait for its …
