Description
Background:
Interleukin-27 (IL-27) is a novel IL-12 family member that plays a role in the early regulation of T helper cell 1 initiation, including induction of T-bet and IL-12 receptor beta 2 expression.1 IL-27 is produced by antigen-presenting cells2 and plays an important function in regulating the activity of B and T lymphocytes.3 IL27 may be a potential therapeutic agent against rheumatoid arthritis (RA) at the onset of the disease.4
Source
E. coli
Molecular Weight
The predicted molecular weight of Recombinant Mouse IL-27 is Mr 23.7 kDa.
State of Matter
Lyophilized
Purity
>97% by SDS-PAGE and HPLC
Storage and Stability
The lyophilized protein should be stored desiccated at -20°C. The reconstituted protein can be stored for at least one week at 4°C. For long-term storage of the reconstituted protein, aliquot into working volumes and store at -20°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
Endotoxin
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Mouse IL-27 was determined by dose-dependent inhibition of TGF-beta & IL-6-induced IL-17A expression in mouse CD4 splenocytes. 50 ng/ml of mouse p28 is capable of inhibiting >25% of IL-17A expression in this assay.
Each investigator should determine their own optimal working dilution for specific applications.
