Detects human CCL3/MIP-1 alpha in direct ELISAs and
Western blots. In direct ELISAs, greater than 75% cross-reactivity with
recombinant human (rh) CCL4/MIP-1 beta is observed while approximately 30%
cross-reactivity with recombinant mouse (rm) CCL3, rmCCL4/MIP-1 beta, and rhCCL14
is observed. No cross-reactivity with rhCCL1, 2, 5, 7, 8, 11, 13, 15, 16, 17,
18, 19, 20, 21, 22, 23, 24, 25, 26, rmCCL1, 2, 5, 6, 7, 9/10/MIP-1 gamma, 11, 12,
17, 19, 20, 21, 22, 24, 25, or recombinant rat CCL20 is observed.

Recombinant Human CCL3/MIP‑1 alpha isoform LD78a (Catalog # 270-LD) under non-reducing conditions only
Immersion fixed human peripheral blood mononuclear cells treated with PHA
Measured by its ability to neutralize CCL3/MIP-1 alpha -induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR5. The Neutralization Dose (ND50) is typically 0.075-0.375 µg/mL in the presence of 10 ng/mL Recombinant Human CCL3/MIP‑1 alpha isoform LD78a.
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 CCL3/MIP‑1 alpha and Neutralization by Human CCL3/CCL4 Antibody. Recombinant Human CCL3/MIP‑1 alpha isoform LD78a (Catalog # 270-LD) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR5 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 CCL3/MIP‑1 alpha isoform LD78a (10 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CCL3/CCL4 Monoclonal Antibody (Catalog # MAB270). The ND50 is typically 0.075‑0.375 µg/mL.

Background: CCL3/MIP-1 alpha
The macrophage inflammatory proteins -1 alpha and -1 beta were originally co-purified from medium conditioned by an LPS-stimulated murine macrophage cell line. Human MIP‑1 alpha refers to the products of several independently cloned cDNAs, including LD78, pL78, pAT464, and GOS19. These cDNAs all code for the same human protein that is a homologue of the murine MIP‑1 alpha. Mature MIP-1 alpha and MIP‑1 beta in both human and mouse share approximately 70% homology at the amino acid level. The MIP‑1 proteins are members of the beta (C-C) subfamily of chemokines. Both MIP‑1 alpha and MIP-1 beta are monocyte chemoattractants in vitro. Additionally, the MIP‑1 proteins have been reported to have chemoattractant and adhesive effects on lymphocytes, with MIP‑1 alpha and MIP‑1 beta preferentially attracting CD8+ and CD4+ T cells, respectively. MIP‑1 alpha has also been shown to attract B cells as well as eosinophils. MIP‑1 proteins have been reported to have multiple effects on hematopoietic precursor cells and MIP‑1 alpha has been identified as a stem cell inhibitory factor that can inhibit the proliferation of hematopoietic stem cells in vitro as well as in vivo. The functional receptor for MIP‑1 alpha has been identified as CCR1 and CCR5.
