Description

The macrophage inflammatory protein-1 alpha  (MIP-1 alpha )/CCL3 and-1 beta (MIP-1 beta )/CCL4 are highly homologous CC family chemokines that were originally co-purified from medium conditioned by an LPS-stimulated murine macrophage cell line. Mouse MIP-1 alpha and MIP-1 beta are encoded by their respective single-copy genes. In human, additional non-allelic MIP-1 alpha and MIP-1 beta genes also exist.The two human MIP-1 alpha genes arise by duplication/mutation. They code for MIP-1 alpha isoforms CCL3/LD78 alpha and CCL3L1/LD78 beta, which share 94% amino acid (aa) sequence homology. Whereas the human CCL3/LD78 alpha is a single-copy gene, the human CCL3L1/LD78 beta gene copy number varies within the population. Human CCL3L1/LD78 beta cDNA encodes a 93 aa residue precursor with a 23 aa residue signal peptide that is cleaved to generate a 70 aa mature protein.

Endotoxin

<  1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.

 

Shipping and Storage
