Recombinant Canine CD28 protein, His-tagged

• Cat.No.: CD28-6754C
• Product Overview: Recombinant Canine CD28 protein(Q9GKP3)(Thr18-Pro153), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Canine
• Source: HEK293
• Tag: His
• Protein Length: Thr18-Pro153
• Tag: C-His
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Molecular Mass: The protein has a predicted MW of 16.7 kDa. Due to glycosylation, the protein migrates to 40-60 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.
