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 monocytes is in a concentration range of 10-100ng/ml.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 150mM NaCl.
Endotoxin
Less than 1EU/μg of rHuLEC/CCL16 as determined by LAL method.
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 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
Human CCL16, also called Liver-expressed chemokine (LEC), Monotactin-1 (MTN-1), IL-10-inducible chemokine and so on, is expressed by the CCL16 gene located on the chromosome 17 in humans. The gene encodes a 120a.a. residue precursor protein with a 23a.a. residue predicted signal peptide that is cleaved to generate a 97a.a. residue mature protein. The protein is secreted by the liver, thymus, spleen cells and showing chemotactic activity for lymphocytes and monocytes but it is distantly related to other CC chemokines, exhibiting less than 30% sequence identity. CCL16 is highly induced by IL-10, IFN-γ and bacterial lipopolysaccharide in monmcytes and signal through CCR1, CCR2, CCR5, and CCR8.
