Recombinant human CCL21 (6CKine) (Cat. No. 582202) (black circles) induces the chemotaxis of mouse Baf3-hCCR7 transfectants. Ultra-LEAF™ purified anti-human CCL21 (6CKine) (clone A15161B) (purple squares) neutralizes the chemotaxis induced by recombinant human CCL21 (6CKine) on mouse Baf3-hCCR7 cells in a dose-dependent manner, whereas the GoInVivo™ purified mouse IgG1, κ isotype control (Cat. No. 400192) (gray triangles) does not have the effect. ND50 range: 0.06 - 0.6 µg/mL

CCL21 is a CC chemokine highly expressed in lymph nodes. CCL21 is only 32% identical to CCL19 at the amino acid level; nevertheless, these chemokines bind to the same receptor CCR7. CCL21 has a unique extension of about 30 amino acids with two extra cysteine residues in its carboxyl terminus. CCL21 is expressed in synovial tissue in rhematoid arthritis (RA), and it has been suggested that CCL21, but not CCL19, induces human microvascular endothelial cell (HMVEC) migration and/or tube formation. In addition, it has been reported that sustained high concentrations of either soluble or immobilized CCL19 and CCL21 inhibit T cell proliferation and IL-2 secretion.

- Distribution
-
CCL21 is highly expressed in HEV of lymph nodes and Peyer's patches. Also, it is expressed in the T cell zones of lymph nodes, in Peyer's patches by reticular cells, and in spleen by stromal cells. CCL21 is expressed by endothelial cells in lymphatic venules.
- Function
- CCL21 chemoattracts naïve T cells and maturing dendritic cells (DCs) into T zones of secondary lymphoid organs. CCL21 and CCL19 chemoattract antigen-engaged B cells to the boundary of B and T zones to interact with T-helper cells. CCL19 and CCL21 inhibit apoptosis in DCs.
- Interaction
- Thymocytes, activated T cells, naïve CD4 and CD8, mature DCs, fibroblast-like synoviocytes of patients with rheumatoid arthritis (RA)

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
