• Cat.No.: POSTN-3919H
• Product Overview: Recombinant Human POSTN protein(Q15063)(Asn22-Gln836) is expressed from HEK293 with His tag at the C-Terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 22-836 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Immobilized Human Periostin, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-Periostin Antibody, hFc Tag with the EC50 of 9.9ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 92.1 kDa. Due to glycosylation, the protein migrates to 93-100 kDa based on Bis-Tris PAGE result.
