Product Description
Recombinant Human Interleukin-4 2ug
Description - Interleukin-4 Human Recombinant produced in E.Coli is
a single, non-glycosylated polypeptide chain containing 130
amino acids and having a molecular mass of 15000 Dalton.
The IL-4 is purified by proprietary chromatographic techniques.
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 - 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 avoid freeze-thaw cycles.
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE
