 Source: HEK-derived.
 The specific activity was determined by the dose-dependent stimulation of the proliferation of mouse D10S cells and is typically 0.02-0.08 ug/ml.
 Purity: > 95% as obsereved by SDS-PAGE.
 Reconstitution: It is recommended to reconstitute the lyophilized IL-1 beta in sterile water not less than 100 ?/ml, which can then be further diluted to other aqueous solutions.
