Scientific Data Images for Human CCL19/MIP-3 beta Antibody
Detection of Human CCL19/MIP‑3 beta by Western Blot.
Western blot shows conditioned media from monocyte-derived macrophages untreated (-) or treated (+) with 1 µg/mL LPS and 40 ng/mL Recombinant Human IFN-gamma (Catalog # 285-IF) for 24 hours. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CCL19/MIP-3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF361) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CCL19/MIP-3 beta at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Chemotaxis Induced by CCL19/MIP‑3 beta and Neutrali-zation by Human CCL19/MIP‑3 beta Antibody.
Re-combinant Human CCL19/MIP-3 beta (Catalog # 361-MI) 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 Human CCL19/MIP-3 beta (50 ng/mL) is neutralized (green line) by increasing concentrations of Human CCL19/MIP-3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF361). The ND50 is typically 2-10 µg/mL.
Detection of Human CCL19/MIP‑3 beta by Simple WesternTM.
Simple Western lane view shows conditioned media from monocyte-derived macrophages untreated (-) or treated (+) with 1 µg/mL LPS and 40 ng/mL Recombinant Human IFN-gamma (Catalog # 285-IF) for 24 hours. A specific band was detected for CCL19/MIP-3 beta at approximately 8 kDa (as indicated) using 50 µg/mL of Goat Anti-Human CCL19/MIP-3 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF361) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Applications for Human CCL19/MIP-3 beta Antibody

Background: CCL19/MIP-3 beta
MIP-3 beta, also known as ELC (EBI1-Ligand Chemokine), is one of many novel beta chemokines identified through bioinformatics. MIP-3 beta cDNA encodes a 98 amino acid (aa) residue precursor protein with a predicted 21 aa residue signal peptide that is cleaved to form the 77 aa residue mature secreted protein. MIP-3 beta is distantly related to other beta chemokines (20-30% aa sequence identity) and the gene for MIP-3 beta has been mapped to chromosome 9p13 rather than chromosome 17 where the genes for many human beta chemokines are clustered. MIP-3 beta has been shown to be constitutively expressed in various lymphoid tissues (including thymus, lymph nodes, appendix and spleen). The expression of MIP-3 beta is down-regulated by the anti-inflammatory cytokine IL-10. MIP-3 beta has been shown to be a unique functional ligand for CCR7 (previously referred to as the Epstein-Barr virus-induced gene 1 (EBI1) orphan receptor), a chemokine receptor that is expressed in various lymphoid tissues and activated B and T lymphocytes. EBI1 is strongly up-regulated in B cells infected with Epstein-Barr virus and T cells infected with herpesvirus 6 or 7.
