Recombinant Human IL5RA protein, His-Avi-tagged

• Cat.No.: IL5RA-340H
• Product Overview: Recombinant Human IL5RA protein(Q01344-1)(Asp21-Glu335), fused with C-terminal His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Asp21-Glu335
• Tag: C-His-Avi
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
• Bio-activity: Human IL-5, His Tag immobilized on CM5 Chip can bind Human IL-5 R alpha, His Tag with an affinity constant of 4.9nM as determined in a SPR assay (Biacore T200).
• Molecular Mass: The protein has a predicted MW of 38.7 kDa. Due to glycosylation, the protein migrates to 50-68 kDa based on Tris-Bis PAGE result.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
• Storage: Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
• Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
