Product details

Human CCL19 ELISA Kit (ab245723) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of CCL19 protein in cell culture supernatant, cit plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human CCL19 with 1.04 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.

Supplementary information

MIP-3 beta also known as CCL19 is a chemokine involved in immune responses. It weighs around 11 kDa and is encoded by the CCL19 gene. MIP-3 beta does its function by binding to its receptor CCR7 which is common in lymph nodes and other lymphoid tissues. It recruits and directs the migration of immune cells especially T cells and dendritic cells navigating them towards lymphoid tissues. This makes MIP-3 beta integral in initiating and modulating immune responses.
Biological function summary

MIP-3 beta helps direct cell trafficking within the lymphoid organs. It is not part of a complex but its interaction with the CCR7 receptor is essential for its biological activity. This binding plays a role in the development of secondary lymphoid organs and immune surveillance. Furthermore MIP-3 beta supports the homing of immune cells to appropriate locations impacting both innate and adaptive immune responses.

Pathways

MIP-3 beta is associated with the chemokine signaling pathway and the immune system pathway. Through these pathways it interacts with proteins like CCR7 and other chemokines that regulate leukocyte migration and activation. These pathways ensure local and systemic immune responses are efficiently orchestrated impacting inflammation and immune regulation.

MIP-3 beta has connections to autoimmune diseases like rheumatoid arthritis and cancer. Its deregulation can result in abnormal immune surveillance contributing to the pathology of these conditions. MIP-3 beta regulates immune cell infiltration and any imbalance may also link it to other inflammatory disorders. Relations to proteins such as CCR7 in these conditions emphasize its role in disease pathogenesis and highlight its potential as a therapeutic target.

Target data

May play a role not only in inflammatory and immunological responses but also in normal lymphocyte recirculation and homing. May play an important role in trafficking of T-cells in thymus, and T-cell and B-cell migration to secondary lymphoid organs. Binds to chemokine receptor CCR7. Recombinant CCL19 shows potent chemotactic activity for T-cells and B-cells but not for granulocytes and monocytes. Binds to atypical chemokine receptor ACKR4 and mediates the recruitment of beta-arrestin (ARRB1/2) to ACKR4.
