Formulation |
Lyophilized from a 0.2um filtered concentrated solution in 1xPBS, pH 7.4. |
Solubility |
It is recommended to reconstitute the lyophilized Interleikin-4 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
Purity |
Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |

IL-4 Rhesus Macaque Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 129 amino acids and having a molecular mass of 14.9kDa.The IL4 Rhesus Macaque is purified by proprietary chromatographic techniques. |
Expression host |
Escherichia Coli. |
Synonyms |
Interleukin-4, IL-4, B-cell stimulatory factor 1, BSF-1, Lymphocyte stimulatory factor 1, IL4. |
Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
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.Please prevent freeze-thaw cycles. |
