Active Recombinant Cynomolgus IgE protein, His & Avi tagged

• Cat.No.: IgE-909C
• Product Overview: Recombinant Cynomolgus IgE protein(G8F4W7)(Lys208-Lys429), fused with C-terminal His tag and Avi tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Cynomolgus
• Tag: His & Avi
• Form: Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Cynomolgus IgE, His Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Anti-IgE Antibody, hFc Tag with the EC50 of 9.3ng/ml determined by ELISA. See testing image for detail.
• Molecular Mass: The protein has a predicted MW of 27.9 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.
• Protein Length: Lys208-Lys429
• Endotoxin: Less than 1EU per ug 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: 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.
