|Product name||Recombinant Human IL-1RN Protein|
|Description||Recombinant Human IL-1RN Protein is produced by E. coli expression system. The target protein is expressed with sequence (Arg26-Glu177) of human IL-1RN (Accession #NP_776214.1) fused with an initial Met at the N-terminus and a 6×His tag at the C-terminus.|
|Bio-Activity||Measured by its ability to inhibit IL-1 alpha-dependent proliferation in D10.G4.1 mouse helper T cells. The ED50 for this effect is 5-40 ng/mL in the presence of 50 pg/mL of rhIL-1 alpha.|
|Synonym||DIRA; ICIL-1RA; IL-1ra; IL-1ra3; IL-1RN; IL1F3; IL1RA; IRAP; MVCD4|
|Expressed Host||E. coli|
|Tag||6×His tag at the C-terminus|
|Purity||> 97% by SDS-PAGE.|
|Endotoxin||< 0.1 EU/μg of the protein by LAL method.|
|Formulation||Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.|
|Storage||Store the lyophilized protein at -20°C to -80 °C for long term.|
