Product details:
Human Exodus 2 ELISA Kit (CCL21) (ab193759) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Exodus 2 (CCL21) protein in cell culture supernatant, cit plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Exodus 2 (CCL21) with 3.8 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Exodus 2 (CCL 21) is a small cytokine in the CC chemokine family, and is involved in inhibition of hemopoiesis and stimulation of chemotaxis. It interacts with atypical chemokine receptor ACKR4 and recruits beta-arrestin to ACKR4.

CCL21 also known as Exodus 2 or 2H26 is a chemokine with significant roles in the immune system. It is a small protein with a molecular mass of approximately 12 kDa. CCL21 is expressed in high concentrations in secondary lymphoid organs such as the spleen lymph nodes and Peyer's patches. It serves as a chemoattractant particularly for lymphocytes and dendritic cells facilitating their migration towards lymphoid organs.
Biological function summary
CCL21 is essential for guiding immune cells to areas where they are needed for initiating immune responses. It forms a non-covalent complex with its receptor CCR7 a primary mechanism through which it exerts its biological effects. CCL21 coordinates the positioning of immune cells within the lymphoid organs ensuring a functional and effective immune response to pathogens or injuries. Its expression pattern aids in the organization of lymphoid tissue architecture and contributes to efficient trafficking of T-cells and dendritic cells.
Pathways
CCL21 plays an important role in the chemokine signaling pathway and the leukocyte transendothelial migration pathway. Within these pathways CCL21 works closely with its receptor CCR7 to guide immune cell navigation and localization. This collaboration is essential for directing cells to appropriate sites in the immune system aligning CCL21 with similar proteins like CCL19 another chemokine that also interacts with CCR7.
CCL21 is associated with several immune-related conditions including rheumatoid arthritis and chronic lymphocytic leukemia. In rheumatoid arthritis CCL21 contributes to the infiltration and retention of immune cells in the synovial tissue while in chronic lymphocytic leukemia it aids in the homing of malignant cells to lymphoid organs. CCL21’s interaction with CCR7 in these diseases highlights its importance not only in immune surveillance but also in the pathology of these disorders.
