CAT No.BT-CYT-363

Interleukin-19 Human Recombinant, IL 19 Human, 10ug

---

Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Arg-Arg-Cys.

Biological Activity
The activity is determined by it's ability to activate STAT following receptor-ligand interaction.

Description
Interleukin-19 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 155 amino acids and having a molecular mass of 17913 Dalton.
The IL-19 is purified by proprietary chromatographic techniques.

Lyophilized from a concentrated (1mg/ml) solution in water containing 10mM sodium citrate pH-5.

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

Purity
Greater than 99.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Interleukin -19 in sterile 18M¦¸-cm H2O at a concentration of 0.5mg/ml or less.

Source
Escherichia Coli.

Stability
Lyophilized Interleukin-19 although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution IL19 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.
