Recombinant Human HHLA2 protein, His-tagged

• Cat.No.: HHLA2-549H
• Product Overview: Recombinant Human HHLA2 protein(Q9UM44-1)(Ile23-Asn344), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: C-His
• Protein length: Ile23-Asn344
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human B7-H7, His Tag at 5 μg/ml (100 μl/well) on the plate. Dose response curve for Human CD28H, hFc Tag with the EC50 of 63.4 ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 38.1 kDa. Due to glycosylation, the protein migrates to 50-70 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.
