Human DPP4 / DPPIV / CD26 Protein

ADABP, ADCP2, CD26, DPPIV, TP103

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Human Cells

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/ug.
2. Using the Octet RED System, the affinity constant (Kd) of human DPP4 (Cat: 10688-HNCH) bound to Spike (HCoV-EMC/2012) (Cat: 40071-V31B) was 20 nM.
3. Using the Octet RED System, the affinity constant (Kd) of human DPP4 (Cat: 10688-HNCH) bound to Spike (HCoV-EMC/2012) (Cat: 40071-V05B) was 50 nM.
4. Using the Octet RED System, the affinity constant (Kd) of human DPP4 (Cat: 10688-HNCH) bound to Spike (HCoV-EMC/2012) (ECD, aa 1-1297) (Cat: 40069-V08B) was 33 nM.
5. Using the Octet RED System, the affinity constant (Kd) of human DPP4 (Cat: 10688-HNCH) bound to Spike-His (aa 1-760) (Cat: 40021-V08H) was 12 nM.
