>98% (SDS-PAGE) . Endotoxin level is less than 0.06EU/ μg protein (LAL test; Lonza) .

Shows the biological function of the IL-4 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.

Lyophilized

Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are stable for up to 3 months when stored at -20°C.
