• Cat.No.: IL13-2191C
• Product Overview: Recombinant Canine IL13 protein(Q9N0W9)(19-131 aa), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Canine
• Source: HEK293
• Tag: His
• Protein Length: 19-131 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: Immobilized Canine IL-13, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human IL-13Ra2, His Tag with the EC50 of 22.2ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 14.05 kDa. Due to glycosylation, the protein migrates to 30-45 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
• 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.
