Amino Acid Sequence

Source Pichia pastoris.
Physical Appearance and Stability Lyophilized Interleukin-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Interleukin-4 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.
Formulation and Purity The protein was lyophilized from 0.2µm filtered solution in 20mM sodium phosphate buffer pH 6.0 in absence of any carrier protein. Greater than 98% as determined by SDS-PAGE.
Solubility It is recommended to reconstitute the lyophilized Interleukin-4 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The biological activity is determined by measuring the dose-dependent proliferation of human TF¿1 cells and CD23 expression. A concentration range of 0.1¿10.0 ng/ml is effective for most in vitro applications. ED50 = 0.05¿0.4ng/ml.
Shipping Format and Condition Lyophilized powder at room temperature.
