Active Recombinant Rat Il4r protein, His-tagged, Low Endotoxin

• Cat.No.: Il4r-11106R
• Product Overview: Recombinant Rat Il4r protein(Q63257-1)(26-232 aa), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Rat
• Source: HEK293
• Tag: His
• Protein Length: 26-232 aa
• Form: Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Rat IL-4 R alpha, His Tag immobilized on CM5 Chip can bind Mouse IL-4, His Tag with an affinity constant of 3.42 nM as determined in SPR assay (Biacore S200).
• Molecular Mass: The protein has a predicted MW of 25.45 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
