More Details about

IL-4 has been known as a Th2 cytokine and can act on B cells, T cells, and monocytes. IL-4 exhibits antitumor activity in rodent experimental gliomas, which is likely mediated by the actions of IL-4 on a variety of immune cells present in and around the tumor masses. rHu IL-4 produced in E. coli is a single, non-glycosylated polypeptide chain that contains 130 amino acids and has a molecular mass of 15 kDa.

Physical Appearance: Sterile filtered white lyophilized (freeze-dried) powder.

Source: E. coli

Formulation: Lyophilized with no additives.

Reconstitution: It is recommended to reconstitute the lyophilized product with sterile water to a concentration of 0.1 mg/ml. It can be further diluted into other aqueous solutions.

Stability: Product is very stable for up to 3 years from manufacturing date, when stored lyophilized at -20° C. Reconstituted material should be aliquoted and frozen at -20° C. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage.

Shipping Conditions: Can be shipped ambient. Product should be stored at -20° C upon receipt.

Purity greater than 98% as determined by:
Analysis by RP-HPLC.
Reducing and non-reducing SDS-PAGE.

Protein Content determined by:
UV spectroscopy at 280 nm.
Analysis by RP-HPLC calibrated against a known standard.
Quantitation on SDS-PAGE against a known standard.

Endotoxin Level: Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.

Biological Activity:
rHu IL-4 is fully biologically active when compared to a  standard. The ED50 as measured by CD23 receptor binding on human peripheral macrophages is less than 1.8 ng/ml.
