Interferon-inducible T Cell Alpha Chemoattractant Active Protein | CXCL11 active protein
Interferon-inducible T Cell Alpha Chemoattractant, Recombinant, Human (I-TAC)
98% as determined by RP-HPLC, anion-exchange FPLC and/or reducing and non-reducing SDS-PAGE Silver Stained gel.
98% as determined by RP-HPLC, anion-exchange FPLC and/or reducing and non-reducing SDS-PAGE Silver Stained gel.
1. UV spectroscopy at 280 nm.
2. Analysis by RP-HPLC, using a calibrated solution of Human I-TAC as a Reference Standard.
Stability: Lyophilized I-TAC although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution I-TAC should be stored at 40C between 2-7 days and for future use below -180C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.
Recombinant Human I-TAC (Interferon-inducible T-cell alpha chemoattractant) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 73 amino acids and having a molecular mass of 8300 Dalton. Recombinant Human I-TAC is purified by proprietary chromatographic techniques.
NCBI and Uniprot Product Information
NCBI Description
Chemokines are a group of small (approximately 8 to 14 kD), mostly basic, structurally related molecules that regulate cell trafficking of various types of leukocytes through interactions with a subset of 7-transmembrane, G protein-coupled receptors. Chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. Chemokines are divided into 2 major subfamilies, CXC and CC. This gene is a CXC member of the chemokine superfamily. Its encoded protein induces a chemotactic response in activated T-cells and is the dominant ligand for CXC receptor-3. The gene encoding this protein contains 4 exons and at least three polyadenylation signals which might reflect cell-specific regulation of expression. IFN-gamma is a potent inducer of transcription of this gene. [provided by RefSeq]
Uniprot Description
Function: Chemotactic for interleukin-activated T-cells but not unstimulated T-cells, neutrophils or monocytes. Induces calcium release in activated T-cells. Binds to CXCR3. May play an important role in CNS diseases which involve T-cell recruitment. May play a role in skin immune responses.
Subcellular location: Secreted.
Tissue specificity: High levels in peripheral blood leukocytes, pancreas and liver astrocytes. Moderate levels in thymus, spleen and lung. Low levels in placenta, prostate and small intestine. Also found in epidermal basal layer keratinocytes in skin disorders.
Induction: By IFNG/IFN-gamma and IFNB1/IFN-beta. Induction by IFNG/IFN-gamma is enhanced by TNF in monocytes, dermal fibroblasts and endothelial cells, and by IL1/interleukin-1 in astrocytes.
Sequence similarities: Belongs to the intercrine alpha (chemokine CxC) family.
Mass spectrometry: Molecular mass is 8303 Da from positions 22 - 94. Determined by MALDI. Ref.4
Sequence caution: The sequence AAB17374.1 differs from that shown. Reason: Erroneous initiation.

Product Notes
The CXCL11 cxcl11 (Catalog #AAA650538) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: The sequence of the first five N-terminal amino acids was determined and was found to be, Phe-Pro-Me t-Phe-Lys. It is sometimes possible for the material contained within the vial of "Interferon-inducible T Cell Alpha Chemoattractant, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
