Synonym(s): IL-1β; Lymphocyte activating factor
Purity: ≥97% (SDS-PAGE)
Physical form: Lyophilized from 0.2 μm filtered solution in 10mM Sodium Citrate, pH 4.0
Analysis Note: The biological activity is measured by the dose-dependent stimulation of murine D10G4.1 cells.
Other Notes: The two closely related agents, Interleukin-1α (IL-1α) and Interleukin-1Β (IL-1Β) bind to the same cell surface receptor, elicit nearly identical biological responses and yet share 25% homology in their amino acid sequence.
Storage: −20°C
Empirical Formula (Hill Notation): C9H7NO2
