Human CCL3/MIP-1 alpha Antibody Summary

Species Reactivity

Human

Specificity

Detects human CCL3/MIP-1 alpha in direct ELISAs and Western blots. In direct ELISAs, less than 20% cross-reactivity with recombinant human (rh) MIP‑1 beta is observed, less than 15% cross-reactivity with recombinant mouse MIP‑1 alpha is observed and less than 1% cross-reactivity with rhMIP‑1δ and rhMPIF‑1 is observed.

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Human CCL3/MIP‑1 alpha isoform LD78a (Catalog # 270-LD)

Neutralization

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 ≤6 µg/mL in the presence of 5 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/MIP‑1 alpha Antibody. Recombinant Human CCL3/MIP-1a (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 HumanCCL3/MIP-1a (5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL3/MIP-1a Polyclonal Antibody (Catalog # AB-270-NA). The ND₅₀ is typically ≤ 6 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.
