Kineret protein solution survives ten years.

ABSTRACT

Proteins are labile and their shelf lives are usually months to few years. Herein we report that human interleukin-1 receptor antagonist (IL-1Ra) solution survives ten years. This provides an interesting case that protein biopharmaceutical aqueous solution could be stored for a decade without losing its quality, which could meet the national security needs for 10 years shelf life of biopharmaceuticals.
