Stability and Reconstitution

Stability and Storage Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20oC) and (-80oC). Upon reconstitution we recommend that the solution can be stored at (4oC) for short term or at (-20oC) to (-80oC) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.
Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 1xPBS containing 0.1% endotoxin-free recombinant human serum albumin (HSA).

Background

Interleukin-1 is a pro-inflammatory cytokine with multiple biological effects. The IL-1 gene family encodes three proteins: IL-1α, IL-1β and their naturally occurring inhibitor Il-1RN. Interleukin 1β(IL-1β), mainly produced by blood monocytes and tissue macrophages, has been implicated in mediating both acute and chronic inflammation. IL-1β is known to be involved in a variety of cellular activities, including cell proliferation, differentiation and apoptosis. IL-1β is emerging as a key mediator of carcinogenesis that characterizes host-environment interactions (PMID: 8630372; PMID: 12401481; PMID: 23704929; PMID: 24618930).
