• Tag:

  Tag-Free

• Type:

  Active Protein & In Stock Protein

• Source:

  E.Coli

• Field of Research:

  Immunology

• Relevance:

  Inhibits hemopoiesis and stimulates chemotaxis. Chemotactic in vitro for thymocytes and activated T-cells, but not for B-cells, macrophages, or neutrophils. Shows preferential activity towards naive T-cells. May play a role in mediating homing of lymphocytes to secondary lymphoid organs. Binds to atypical chemokine receptor ACKR4 and mediates the recruitment of beta-arrestin (ARRB1/2) to ACKR4.

• Endotoxin:

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

• Purity:

  >95% 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 lymphocytes is in a concentration range of 10-100 ng/ml.

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 µm filtered concentrated solution in 2 x PBS, pH 7.0.

• 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.

• Molecular Weight:

  12.2 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.
