Detects mouse CCL19/MIP-3 beta in direct ELISAs and Western blots. In direct ELISAs, less than 30% cross-reactivity with recombinant rat CCL19/MIP-3 beta is observed and less than 10% cross-reactivity with recombinant human CCL19/MIP‑3 beta is observed.
Measured by its ability to neutralize CCL19/MIP‑3 beta -induced chemotaxis inthe BaF3 mouse pro-B cell line transfected with human CCR7. The Neutralization Dose (ND50) is typically 0.8-4 μg/mL in the presence of 50 ng/mL Recombinant Mouse CCL19/MIP‑3 beta.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by CCL19/MIP‑3 beta and Neutralization by Mouse CCL19/MIP‑3 beta Antibody. Recombinant Mouse CCL19/MIP‑3 beta (Catalog # 440-M3) chemoattracts the BaF3 mouse pro-B cell line transfected with human CCR7 in a dose-dependent manner (orange line).The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Mouse CCL19/MIP‑3 beta (50 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse CCL19/MIP‑3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF880). The ND50 is typically 0.8-4 μg/mL.
CCL19/MIP‑3 beta in Mouse Splenocytes. CCL19/MIP‑3 beta was detected in immersion fixed mouse splenocytes using Goat Anti-Mouse CCL19/MIP‑3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF880) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow; Catalog # NL001) and counterstained with DAPI (blue).

CCL19/MIP‑3 beta in Mouse Dendritic Cells. CCL19/MIP‑3 beta was detected in immersion fixed mouse dendritic cells using Goat Anti-Mouse CCL19/MIP‑3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF880) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Background: CCL19/MIP-3 beta
CCL19/MIP-3 beta, also known as ELC (EBI1-Ligand Chemokine), is a reported beta chemokine that binds specifically to the chemokine receptor CCR-7/EBI-1/BLR-2. Mouse (human) MIP-3 beta cDNA encodes a 108 (98) amino acid residue precursor protein with a predicted 25 (21) aa residue signal peptide that is cleaved to form the 83 (77) aa residue mature secreted protein. MIP-3 beta is distantly related to other beta chemokines (20-30% aa sequence identity). Mouse MIP-3 beta shares 83% aa sequence homology with human MIP-3 beta. MIP-3 beta has been shown to be constitutively expressed in various lymphoid tissues (including thymus, lymph nodes, appendix, and spleen) in dendritic cells within the T cell zone. The expression of MIP-3 beta is down-regulated by the anti-inflammatory cytokine IL-10. Recombinant MIP-3 beta has been shown to be chemotactic for T cells and B cells. The MIP-3 beta receptor (CCR7/EBI-1/BLR-2) is expressed in various lymphoid tissues and activated B and T lymphocytes. CCR7 is also strongly up-regulated in B cells infected with Epstein-Barr virus and T cells infected with herpes virus 6 or 7.
