Description

CCL23 is a member of CC chemokine family and is encoded by CCL23 gene located on Chr.17 in humans, where near several other CC chemokines. Highly expressed in adult lung, liver, skeletal muscle and pancreas, this protein shows strong chemotactic activity for monocytes, resting T-lymphocytes, and neutrophils, but not for activated lymphocytes. It elicits the effects by binding to CCR1. CCL23 is reported that it can be cleaved into four forms: CCL23 (19-99), CCL23 (22-99), CCL23 (27-99), CCL23 (30-99).

Molecular Weight

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 97 % by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration of 10-50 ng/ml.

Endotoxin

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

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.

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.
