Catalog #: CYT-212
Description:
Interleukin-5 Human Recombinant produced in E.Coli is a dimeric, non-glycosylated polypeptide chain containing 132 amino acids and having a molecular mass of 26522.84 Dalton.
The IL-5 is purified by proprietary chromatographic techniques.
Synonyms:
EDF, BCDFII, TRF, T-cell replacing factor, Eosinophil differentiation factor, B cell differentiation factor I, IL-5.
Source:
Escherichia Coli.
Amino Acid Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ile-Pro-Thr-Glu.
Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Interleikin-5 in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
Lyophilized from a concentrated (1mg/ml) solution in water containing no additives.
Stability:
Lyophilized Interleukin-5 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL5 should be stored at 4 °C between 2-7 days and for future use below -18 °C.
Please avoid freeze thaw cycles.
Activity:
The ED50 as determined by the dose-dependant stimulation of the proliferation of TF-1 cells was found to be < 0.15ng/ml, corresponding to a Specific Activity of 6 x 106 IU/mg.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
