Human recombinant CCL2 (C-C motif chemokine ligand 2) protein, AF

C-C Motif Chemokine Ligand 2 (CCL2) is an 8.44 kDa cytokine with 76 amino acid residues and is also known as monocyte chemoattractant protein 1 (MCP1) . The CCL2 secreted from monocytes, macrophages, and dendritic cells. Upon binding with CCR4, it regulates many biological functions, such as recruitments of monocytes, memory T cells, and dendritic cells, response to TNF-α and Interferon-γ, angiogenesis, cellular homeostasis, and cytoskeleton organization.

Applications

Cell Culture

Purification

>95% as determined by SDS-PAGE.

Endotoxin

<0.1 EU per 1 μg of the protein by the LAL method.

Bioactivity

Measure by its ability to chemoattract BaF3 cells transfected with human CCR2A. The ED50 for this effect is <20 ng/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 7.4. If you have any concerns or special requirements, please confirm with us.

Reconstitution

Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.

Molecular Weight

The protein has a calculated MW of 9.49 kDa. The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis) .

Storage Conditions

Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
