Mouse IL 4

 - 

Interleukin-4 Mouse Recombinant



Synonyms:

BCGF, BCDF, B cell stimulating factor, BSF-1, Lymphocyte stimulatory factor 1, IL 4, MGC79402, Binetrakin, Pitrakinra.



Description:

Interleukin-4 Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 120 amino acids and having a molecular mass of 13500 Dalton.
The IL 4 is purified by proprietary chromatographic techniques.



Source:

Escherichia Coli.



Physical Appearance:

Sterile Filtered White lyophilized (freeze-dried) powder.



Formulation:

Lyophilized from a concentrated (1mg/ml) solution in water containing no additives.



Solubility:

It is recommended to reconstitute the lyophilized Interleukin 4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.



Stability:

Lyophilized Interleukin-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL4 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).


Please prevent freeze-thaw cycles.

Purity:

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.



Amino acid sequence:

The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Ile-His-Gly.



Biological Activity:

The ED50 as determined by the dose-dependant prolifiration of Murine HT-2 cells is < 2 ng/ml, corresponding to a Specific Activity of 5x105 IU/mg.



Usage:
