Host Species | Human |
Synonym | Small inducible cytokine A21, CCL21, Beta chemokine exodus-2, 6Ckine, Secondary lymphoid-tissue chemokine, SLC, chemokine (C-C motif) ligand 21, ECL, CKb9, TCA4, SCYA21, MGC34555. |
Background | Chemokine (C-C motif) ligand 21 (CCL21) is a small cytokine belonging to the CC chemokine family. This chemokine is also known as 6Ckine (because it has six conserved cysteine residues instead of the four cysteines typical to chemokines), exodus-2, and secondary lymphoid-tissue chemokine (SLC). CCL21 is expressed predominantly in the lymph nodes and, in contrast to other CC chemokines, is chemotactic for lymphocytes. The gene for CCL21 is located on human chromosome 9. CCL21 elicits its effects by binding to a cell surface chemokine receptor known as CCR7. |
Description | Exodus-2 Human Recombinant expressed in E.Coli as a single, non-glycosylated, polypeptide chain containing 111a.a. and having a molecular weight of 12219 Dalton. The CCL21 is purified by unique purification methods. |

Purity | >97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Endotoxin | <1.0 EU per μg by the LAL method. |
Bioactivity | Determined by its ability to chemoattract human total lymphocyte population using a concentration range of 10-100ng/ml. |
Formulation | Lyophilized from a 0.2µm filtered concentrated solution in 20mM Phosphate Buffer, pH 7.4 and 150mM NaCl. |
Stability | Recombinant protein is stable for 12 months at -70°C |
Usage | For Research Use Only |
Storage | Lyophilized Exodus-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL21 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
