Applications Dilution Species-Reactivity Sensitivity MW (kDa) Isotype

Species cross-reactivity is determined by western blot.

Applications Key:

Source / Purification

Recombinant Mouse MCP-1 (mMCP-1) Gln24-Arg96 (Accession #NP_035463) was expressed in E.coli at Cell Signaling Technology.

Quality Control

>93% as determined by SDS-PAGE of 6 μg reduced (+) and nonreduced (-) recombinant mMCP-1. All lots are greater than 93% pure.

Molecular Characterization

Molecular Characterization: Recombinant mMCP-1 has a calculated MW of 8,530. DTT-reduced protein migrates as a 8 kDa polypeptide. The nonreduced protein migrates at 12 kDa. The expected amino-terminal QPDAV of recombinant mMCP-1 was verified by amino acid sequencing.

Bioactivity

The activity of mMCP-1 was determined using a THP-1 cell migration assay. The ED50 of each lot is between 1-11 ng/ml.

Bioactivity

Bioactivity

mMCP-1-induced migration of THP-1 cells was assessed. THP-1 cells were incubated in a 96-well transwell plate with increasing concentrations of mMCP-1 in the bottom chamber. After 2 hr, the number of THP-1 cells that migrated to the bottom chamber of the transwell was quantified by measuring DNA content using a fluorescent dye.

Coomassie Gel

Coomassie Gel

The purity of recombinant mMCP-1 was determined by SDS-PAGE of 6 µg reduced (+) and nonreduced (-) recombinant mMCP-1 and staining overnight with Coomassie Blue.

Applications

Optimal concentration for the desired application should be determined by the user.

Endotoxin

Less than 0.01 ng endotoxin/1 μg mMCP-1.

Formulation

With carrier: Lyophilized from a 0.22 μm filtered solution of mMCP-1 in 20 mM Tris, pH 7.2 containing 20 μg BSA per 1 μg mMCP-1. Carrier free: Lyophilized from a 0.22 μm filtered solution of mMCP-1 in 20 mM Tris, pH 7.2.

Background

MCP-1 (CCL2) is the first member of the C-C family of chemokines to be identified (1). C-C chemokines are characterized by two adjacent cysteine residues within the polypeptide, which form an intra-molecular disulfide bond. MCP-1 is a potent chemotactic factor for monocytes/macrophages, T cells and a subset of NK cells (1-4). The MCP-1 receptor, CCR2, is expressed as two splice isoforms, CCR2A and CCR2B, of which CCR2B is the predominant form (1). MCP-1 is secreted by adipocytes and appears to be one of many links between obesity, inflammation, and diabetes (1). MCP-1/CCR2 signaling appears to play a key role in γδ effector T cells recruitment and anti-tumor responses in a murine B16 melanoma model (2). Conversely, CCL2 expression is upregulated in many types of cancer and has been implicated in promoting tumor cell survival, proliferation, and tumor associated inflammation (4).
