Active Recombinant Human DPP4 protein

• Cat.No.: DPP4-270H
• Product Overview: Active Recombinant Human DPP4 protein(NP_001926.2) extracellular domain (Asn 29-Pro 766) was expressed and purified in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Non
• Protein Length: 29-766 aa
• Form: Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5.
• Bio-activity: 1. Measured by its ability to cleave the fluorogenic peptide substrate, Gly-Pro-7-amido-4-methylcoumarin (GP-AMC). The specific activity is > 2,500 pmoles/min/μg. 2. Using the Octet RED System, the affinity constant (Kd) of human DPP4 bound to Spike (HCoV-EMC/2012) was 20 nM. 3. Using the Octet RED System, the affinity constant (Kd) of human DPP4 bound to Spike (HCoV-EMC/2012) was 50 nM. 4. Using the Octet RED System, the affinity constant (Kd) of human DPP4 bound to Spike (HCoV-EMC/2012) (ECD, aa 1-1297) was 33 nM. 5. Using the Octet RED System, the affinity constant (Kd) of human DPP4 bound to Spike-His (aa 1-760) was 12 nM.
• Molecular Mass: The recombinant human DPPIV exists as the mature active form, and consists of 738 amino acids with a predicted molecular mass of 85.4 kDa. The apparent molecular mass of the glycosylated rhDPPIV is approximately 95 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 70 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
