Recombinant Human IL1RN protein, hFc-tagged

• Cat.No.: IL1RN-314H
• Product Overview: Recombinant Human IL1RN protein(NP_776214.1) (Arg 26-Glu 177) was expressed in HEK293, fused with the Fc region of human IgG1 at the N-terminus.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Protein length: 26-177 a.a.
• Form: Lyophilized from sterile PBS, pH 7.2. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human IL1RA/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 389 amino acids and predicts a molecular mass of 43.8 kDa. As a result of glycosylation, the rh IL1RA/Fc monomer migrates as approximately 45-55 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per ug of the protein as determined by the LAL method
• Purity: > 98 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
