Product Specific Information

Description: CCL19, also known as MIP-3 beta (Macrophage Inflammatory Protein 3 beta), is a member of the CC- subfamily of chemokines. It is most closely related to CCL21, with which it shares 32% amino acid sequence homology. CCL19 and CCL21 are expressed mainly by stromal cells in the T cell-rich zones of lymph nodes. They are critical mediators of the homeostatic trafficking of naive T cells and activated dendritic cells into the secondary lymphoid organs. CCL19 and CCL21 also play a role in T cell priming and activation, as well as the recruitment of lymphocytes to inflamed tissue. Both proteins signal via the G protein-coupled receptor, CCR7, which is expressed on T cells and mature dendritic cells. Although CCL19 and CCL21 both exhibit the same affinity for CCR7, only the binding of CCL19 results in the desensitization and internalization of the receptor.

Applications Reported: Human CCL19 (MIP-3 beta) Recombinant Protein Carrier-Free is biologically active and can promote chemotaxis of human T cells in culture.

Applications Tested: The bioactivity of this protein was determined by its ability to chemoattract human T cells using a concentration of 10-50 ng/mL.

Source: E. coli-expressed amino acids Gly22-Ser98 (Accession #NM_006274).

Bioactivity: The bioactivity of this protein was determined by its ability to chemoattract human T cells using a concentration of 10-50 ng/mL.

Endotoxin: Less than 0.1 ng/ug cytokine as determined by the LAL assay. Purity: >98% as determined by SDS-PAGE and HPLC.

Molecular Weight: 8.8 kDa.

Storage and handling: Use in a sterile environment. Store lyophilized protein at less than or equal to -20°C. Reconstituted protein solution can be stored with carrier protein (e.g., 0.1% BSA) at less than or equal to -20°C.
