Functional Studies (Func), SDS-PAGE (SDS)
Characteristics 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.

Protein Structure: A DNA sequence encoding the human PGA4 (P00790) (Met 1-Ala 388) was fused with the Fc region of human IgG1 at the C-terminus.
Predicted N-Term: Ile 16
Purity > 80 % as determined by SDS-PAGE
Endotoxin Level < 1.0 EU per μg of the protein as determined by the LAL method
Biological Activity Comment 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)
