IL 19 Human

Interleukin-19 Human Recombinant

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.

Accession

Q9UHD0

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.

Formulation

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 18MΩ-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 -18oC. Upon reconstitution IL19 should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please avoid multiple freeze-thaw cycles.

Synonyms

Melanoma differentiation association like protein, MDA1, NG.1, ZMDA1, IL-10C, IL-19.
