Recombinants or rec. proteins

Protein purity

Greater than 95% as determined by reducing SDS-PAGE.

Reconstitution conditions

See included datasheet or contact us for more information.


Package form

Lyophilized from a 0.2 µm filtered solution of PBS, pH7.4.

Peptide sequence




Recombinant Cavia porcellus Interleukin-1 Beta is produced by our E.coli expression system and the target gene encoding Thr115-Ser266 is expressed with a 6His tag at the C-terminus.

Storage conditions

Lyophilized protein should be stored at below -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 below -20°C for 3 months.


The Interleukin-1 family (IL-1 family) is a group of 11 cytokines, which plays a central role in the regulation of immune and inflammatory responses to infections or sterile insults. Rec. E. coli interleukin-1 for cell culture or antibody production.
