Biological Activity

Description

Eotaxin/CCL11 Protein, Mouse is a potent chemoattractant for eosinophil cells and provides a new mechanism to explain tissue eosinophilia.

Background

CCL11 is a small cytokine belonging to the CC chemokine family. CCL11 selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergicresponses[1]. It is produced by IFN-γ-stimulated endothelial cells and TNF-activated monocytes. CCL11 is a potent chemoattractant for eosinophils, basophils, and Th2 lymphocytes. CCL11 has a number of important biological functions in disease processes. It plays a critical role in allergic and nonallergic inflammatory reactions, such as mycobacterial and schistosomal induced granulomatosis[2].

In Vivo

In CCL11-/- BALB/c mice, methylcholanthrene (MCA) at a concentration of 100 μg can induce fibrosarcoma in 90% of mice, possibly associated with a reduction in eosinophil influx into the tumor, which directly kills MCA-induced fibrosarcoma cells[2].
       CCL11 expression is produced in the peritoneum, serum and lung and peaked after 4 h  intraperitoneal injection of 500 μg lipopolysaccharide (LPS) in 1 mL saline in murine model of sublethal endotoxemia. When eotaxin/CCL11 knockout mice are treated with LPS, there is an increase in peritoneal neutrophils, but not lung neutrophils, compared to wild-type controls. CCL11-/- mice suppresses peritoneal neutrophils associated with endotoxemia[3].

Verified Bioactivity

1.Full biological activity determined by a chemotaxis bioassay using purified eosinophils is in a concentration range of 100-1000 ng/mL.
2.Measured in a cell proliferation assay using HUVEC human umbilical vein endothelial cells. The ED50 for this effect is 1-5 ng/mL.
3.Measured by its ability to chemoattract BaF3-CCR3 cells. The ED50 for this effect is 4.9-5.0 ng/mL, corresponding to a specific activity is 2.029×105 U/mg.

Product Properties

Appearance

Lyophilized powder

Formulation

1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.8.
Please refer to the lot-specific COA for specific buffer information.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
