Recombinant Human CCL22

• Description:

  CCL22 (monocyte-derived chemokine) was described initially as a constitutively produced, thymus-specific chemokine, implicated in the recruitment of T cells . One of the functions of CCL22 originally described was induction of migration of CCR4+ Th2 cells, but it has additionally been shown to regulate migration of Tregs. CCL22 has been implicated in a number of diseases, including allergen-induced lung inflammation, atopic dermatitis, and lymphoma. Similarly, a presumed role for CCR4+ cells has been suggested for endotoxic shock, rheumatoid arthritis, T cell lymphoma, and autoimmune diabetes

  Recombinant Human Macrophage-Derived Chemokine (CCL22)

• Gene ID:

  6367

• Accession Number:

  O00626

• 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:

  The ED(50) was determined by the dose-dependent proliferation of MGC823 cells and was found to be <5ng/mL.

• Molecular Weight:

  8

• 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:

  Lyophilized from 0.2 μm filtered solution in Tris and NaCl, pH 7.0.

• CAS Number:

  9000-83-3
