Description:

Background: IL-4 can signal through type I and type II receptor complexes, which share a common gamma chain. The type I receptor contains in addition to the gamma chain an IL-4R alpha subunit, whereas the type II receptor contains the IL-13R alpha. The se

Molecular Weight:

23.7 kDa

Physical State:

Lyophilized

Formulation:

Lyophilized from a sterile filtered solution without additives.

Purity:

>97% by SDS-PAGE and HPLC analyses

Biological Activity:

ED50: <5.0 ng/ml (as determined by its ability to inhibit the IL-4 dependent proliferation of human TF-1 in the presence of 0.5 ng/ml of IL-4).

Specific Activity:

>2 x 105 u/mg

Endotoxin Level:

<1/�g

Reconstitution:

Centrifuge vial prior to opening. Reconstitute in sterile ddH2O to a concentration of 0.1-1.0 mg/ml. The solution can then be further diluted in other aqueous buffers.

Storage/Stability:

Lyophilized protein is stable at room temperature for few weeks, but is preferably stored at -20℃C. After reconstitution, stored for 1 week at 2-4℃C. For long term storage, aliquot and store at -20℃C. Avoid repeated freeze-thaw cycles.
