Product Overview : |
Recombinant Mouse Ccl17 protein was expressed in Escherichia coli. |
Description : |
Murine CCL17 also known as TARC, Small-inducible cytokine A17, Thymus and activation-regulated chemokine and SCYA17, is encoded by the CCL17 gene located on the chromosome 8. Among CC chemokine family members, CCL17 has approximately 24 – 29 % amino acid sequence identity with RANTES, MIP-1α, MIP-1β, MCP-1, MCP-2, MCP-3 and I-309. CCL17 is a secreted protein and expressed by thymus cells constitutively and phytohemagglutinin-stimulated peripheral blood mononuclear cells transiently. It signals through the chemokine receptors CCR4 and CCR8 and displays chemotactic activity for T lymphocytes and some other leukocytes. CCL17 play an important role in skin diseases such as atopic dermatitis, bullous pemphigoid and mycosis fungoides.Recombinant CCL17 has been shown to be chemotactic for T cell lines but not monocytes or neutrophils. |

Storage : |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution. |
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 centigrade. Further dilutions should be made in appropriate buffered solutions. |
