Beschreibung

Allgemeine Beschreibung

CXCL11 (C-X-C motif chemokine 11), also referred to as I-TAC (interferon-inducible T-cell α chemoattractant), is from to the CXC chemokine family and is an antagonist for CC chemokine receptor 3 (CCR3) and CCR5.[1] CXCL11 was first identified in astrocytes via cDNA sequencing. It can be induced by IFN (interferon)-γ in different cells. CXCL11 interacts with and signals via CXCR3 (C-X-C chemokine receptor type 3).[2]
Recombinant murine I-TAC is a 9.0kDa protein containing 79 amino acid residues including the four highly conserved cysteine residues present in CXC chemokines.

Biochem./physiol. Wirkung

CXCL11 (C-X-C motif chemokine 11) is involved in the wound repair in skin cells.[3] CXCL11′s interaction with CXCR3 (C-X-C chemokine receptor type 3) polarizes naive T cells into IL (interleukin)-10^hi Tregs (regulatory T cells, Tr1) and repolarizes CXCR3⁺CD4⁺ EAE (experimental autoimmune encephalomyelitis)-associated effector T cells into IL-10^hi Tregs.[4] CXCL11 also enhances Th2 (T helper 2) response in model leishmaniasis system, and thereby regulates the outcome of the immunological pathway.[1] In mice model, CXCL11 is upregulated in RSV (respiratory syncytial virus) and influenza A infections.[5]

Physikalische Form

Lyophilized with no additives.

Rekonstituierung

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
