Cat. No. : F9-4350H
Description : Human Factor IX also called Christmas-Factor is a glycoprotein, which is synthesized in the liver and belongs to the serine proteases system and is part of the S1 peptidase family. Lack of Factor-IX causes Hemophilia-B meaning Christmas Disease. Factor-IX has a N-terminus region which contains 12xGla residues which asist the calcium dpendant binding of Factor-IX to the phospholipid surface. Factor-IX is activated by either factor XIa or the factor VIIa/tissue factor/phospholipid complex. Cleavage yields the intermediate IXa, which is subsequently converted to the fully active form IXab. Factor-IX binds initially to exosites on the factor XIa heavy chain, followed by interaction at the active site with subsequent bond cleavage. Coagulation factor IX is activated by interaction with the erythrocyte membrane, causing intrinsic coagulation. Chaperones & lectins act simultaniously to guarantee the proper folding of Factor-IX and the retention of mutant molecules. Human Factor IX, activated by either the Contact or Tissue Factor Pathway, is responsible for the activation of Factor X to Xa.
Source : Human
Host : Human Plasma
Form : The Factor-IX was lyophilized from a sterile solution containing 20mM Tris-HCl pH-7.4, 0.1M NaCl and 1mM Benzamidine.
Purity : Greater than 95% as determined by SDS-PAGE.
Bio-activity : The activity per mg was tested and found to be 195 Units per mg.
Physical Appearance : Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility : It is recommended to reconstitute the lyophilized 100U Factor-IX in sterile 100µl of 18Mμ-cm H2O, which can then be further diluted to other aqueous solutions.
Storage : Lyophilized Factor-IX although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Factor-IX should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.

    The short half-life makes this product very safe.

    10/10/2020

      This protein has a wide range of applications and can be used in a variety of experiments.

      03/27/2019

        The method of use is simple, which reduces the experimental time and improves the efficiency.

        Q&As (6)

        Ask a question
        What is the function of F9 protein? 12/18/2019

        The F9 protein is involved in step IX in the coagulation cascade, which works synergistically with other coagulation factors to promote the normal progress of blood clotting.

        How do genetic mutations in the F9 protein affect its function? 12/04/2019

        Mutations in the F9 gene may lead to loss of protein expression, structural abnormalities, or dysfunction, which in turn affect the normal function of the F9 protein.

        Do F9 protein mutations cause other diseases or affect other physiological processes? 05/27/2019

        F9 protein mutations are primarily associated with hemophilia B, but the specific mutation type and location may have different effects on an individual's clinical presentation.

        What diseases can F9 gene mutations cause? 05/22/2019

        Mutations in the F9 gene may cause hemophilia B, an inherited coagulation disorder in which patients lack the F9 protein or have low activity and are prone to abnormal bleeding.

        How is the activity of F9 protein determined? 04/08/2019

        The activity of the F9 protein is usually measured by coagulation time or by specific experimental methods (eg, prothrombin time, activated partial thromboplastin time, etc.).

        What is the structure of F9 protein? 01/31/2019

        F9 protein is a single-chain glycoprotein consisting of 415 amino acids. It contains a signaling peptide and multiple functional regions in which the Gla domain at the C-terminal binds to calcium ions and the EGF-like domain at the N-terminus participates in receptor binding and activation.
