Detects human CCL15/MIP‑1δ in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant human (rh) MPIF-1 is observed and less than 1% cross‑reactivity with rhMIP-1 alpha is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human CCL15/MIP-1δ Gln22-Ile113 Accession # Q16663
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Recombinant Human CCL15/MIP‑1δ 92 aa (Catalog # 363-MG)
Measured by its ability to neutralize CCL15/MIP‑1δ-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR1. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 0.1 µg/mL Recombinant Human CCL15/MIP‑1δ 92 aa.
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 CCL15/MIP‑1δ and Neutralization by Human CCL15/MIP‑1δ Antibody. Recombinant Human CCL15/MIP‑1δ (Catalog # 363‑MG) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR1 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 CCL15/MIP‑1δ (0.1 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL15/MIP‑1δ Antigen Affinity-purified Polyclonal Antibody (Catalog # AF363). The ND50 is typically 1‑5 µg/mL.

Background: CCL15/MIP-1 delta
CCL15, a human CC chemokine, was isolated from a human fetal spleen cDNA library. CCL15 cDNA encodes a predicted 113 amino acid (aa) protein containing a putative signal peptide of 21 aa that is cleaved to generate a 92 aa residue mature protein. Within the CC family members, human CCL15 shares 45%, 44%, 35%, and 30% aa homology with mouse C10, human MPIF-1, human HCC-1, and mouse MIP-1 gamma, respectively. The gene for MIP-1δ is found on chromosome 17 where the genes for most of the human CC chemokines are located. Human CCL15 is expressed in T and B lymphocytes, NK cells, monocytes and monocyte-derived dendritic cells. Human MIP-1δ is chemotactic for T cells and monocytes and has been shown to induce calcium flux in human CCR-1-transfected cells.
