Description
Recombinant Human Interleukin-4 Receptor Subunit Alpha is produced by our Mammalian expression system and the target gene encoding Met26-His232 is expressed with a 6His tag at the C-terminus.
Alias
Interleukin-4 receptor subunit alpha; IL-4 receptor subunit alpha; IL-4R subunit alpha; IL-4R-alpha; IL-4RA; CD124; IL-4-binding protein; IL4-BP; IL4R; IL4RA
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by its ability to inhibit IL-4-dependent proliferation of TF‑1 human erythroleukemic cells.The ED50 for this effect is less than 20 ng/ml.
Formulation
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
Storage
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Warranty
For Research Use Only. Our recombinant proteins can not be used in diagnostic procedures.
