Recombinant Human CCL21

• Description:

  CCL21, which is a member of the family of CC-Chemokines, has a unique 36 (murine) or 37 (human) amino acid carboxyl-terminal extension not seen in other chemokines. CCL21 selectively stimulates the chemotaxis of adult T lymphocytes and is expressed preferentially in lymph node tissue. CCL21 is critical for adult T cell adhesion to high endothelial venules in lymph nodes, a rate-limiting step for T cell trafficking through nodal tissue.

• Gene Name:

  CCL21

• Gene Aliases:

  C-C motif chemokine 21, 6Ckine, Beta-chemokine exodus-2, SLC, Small-inducible cytokine A21, SCYA21
  Recombinant Human Secondary Lymphoid-Tissue Chemokine (CCL21)

• Gene ID:

  6366

• Accession Number:

  O00585

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method.

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

• Function:

  Determined by its ability to chemoattract total lymphocyte population using a concentration range of 10-100 ng/mL.

• Molecular Weight:

  12

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

  The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

• Appearance:

  Lyophilized Powder

• Formulation:

  Recombinant CCL21 was lyophilized from a 0.2 μm filtered solution in 2.5% glycine, 0.5% sucrose, 0.01% Tween80, 5 mM Glutamic acid, pH 4.5.

• CAS Number:

  9000-83-3
