• Abbreviation:

  Recombinant Human PF4 protein (Active)

• Gene Name:

  PF4

• UniProt:

  P02776

• Expression Region:

  32-101aa

• Organism:

  Homo sapiens (Human)

• Target Sequence:

  EAEEDGDLQCLCVKTTSQVRPRHITSLEVIKAGPHCPTAQLIATLKNGRKICLDLQAPLYKKIIKKLLES

• Tag:

  Tag-Free

• Type:

  Active Protein & In Stock Protein

• Source:

  E.Coli

• Field of Research:

  Immunology

• Relevance:

  Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form. {ECO:0000269|PubMed:7644496}.

• Endotoxin:

  Less than 1.0 EU/μg as determined by LAL method.

• Purity:

  >97% as determined by SDS-PAGE.

• Activity:

  Yes

• Bioactivity:

  Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human fibroblasts is in a concentration of 1.0-10 ng/ml.

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 μm filtered concentrated solution in Acetonitrile and TFA.

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Function:

  Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form.

• Molecular Weight:

  7.8 kDa

• Storage Conditions:

  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
