P05112
Source
E. coli
Field of Research
Immunology & Inflammation
Purity
Greater than 98% by SDS-PAGE gel and HPLC analyses.Endotoxin level is less than 0.1 ng per μg (1EU/μg) .
Bioactivity
The ED50 was determined by the dose - dependent stimulation of human TF - 1 cells is ≤ 0.2 ng/mL, corresponding to a specific activity of ≥ 5 x 106 units/mg.
Form
Lyophilized
Storage Conditions
The lyophilized IL-4 recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted IL-4 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing IL-4 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
