Description
Recombinant Human Interleukin-1 beta is produced by our E.coli expression system and the target gene encoding Ala117-Ser269 is expressed.
Alias
Interleukin-1 beta; Catabolin; IL1F2; IL1B.
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by its ability to induce NFKB reporter gene expression in HEK 293 cell line.The ED50 for this effect is typically 142 pg/mL
Formulation
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Storage
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.
