• Cat.No.: PGA4-478H
• Product Overview: Recombinant Human PGA4 protein(NP_001073276.1)(Met1-Ala388), fused with hFc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• ProteinLength: Met1-Ala388
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2, AnaSpec, Catalog # 27114.The specific activity is > 3000 pmoles/min/μg.(Activation description: The enzyme achieves its activity under acidic pH)
• Molecular Mass: The secreted recombinant human PGA4/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 614 amino acids and has a predicted molecular mass of 67.3 kDa. The apparent molecular mass of rhPGA/Fc monomer is approximately 65-70 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 80 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. 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.
