Recombinant Human SIRPA protein, His-Avi-tagged

• Cat.No.: SIRPA-2434H
• Product Overview: Recombinant Human SIRPA protein(P78324 variant 4)(Glu31-Arg370(E33G, L44S, T50S, T52I, R54H)), fused with C-terminal His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Glu31-Arg370(E33G, L44S, T50S, T52I, R54H)
• Tag: C-His-Avi
• 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 SIRP alpha V4, His Tag at 1ug/ml (100ul/Well). Dose response curve for Human CD47, hFc Tag with the EC50 of 44.3ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 39.8 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.
