I-TAC Human Recombinant (CXCL11), I TAC Human, 20ug

---

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.

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be, Phe-Pro-Met-Phe-Lys.

Biological Activity
ED50 range=1-10ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg determined by the dose dependent chemotaxis of human lymphocytes cultured in the presence of IL-2.

The CXCL11 was lyophilized from a concentrated (1mg/ml) solution in water containing no additives.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized I-TAC in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized I-TAC although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CXCL11 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
