Human I-TAC protein

• Catalog Number: orb80138
• Category: Proteins
• Description: I-TAC Human Recombinant (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. The I-TAC is purified by proprietary chromatographic techniques.
• Tested applications: FA, HPLC, SDS-PAGE
• Purity: > 95.0% as determined by RP-HPLC and analysis by SDS-PAGE
• Conjugation: Unconjugated
• Target: I TAC
• Solubility (25°C): It is recommended to reconstitute the lyophilized I-TAC in sterile H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be, Phe-Pro-Met-Phe-Lys.
• Biological Origin: E.coli
• Biological Activity: ED50 range=1.0-10 ng/mL, determined by the dose dependent chemotaxis of human lymphocytes cultured in the presence of IL-2.
• Storage: Store at 4°C for up to two weeks. For long term storage, aliquot and store at -20°C, avoid freeze/thaw cycles.
• Buffer/Preservatives: The CXCL11 was lyophilized from concentrated (1mg/ml) solution in water containing no additives.
• Note: For research use only
• Expiration Date: 6 months from date of receipt.
