This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 80.7 kDa. The protein migrates as 90 kDa±3 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with protectants.

This product is supplied and shipped with blue ice, please inquire the shipping cost.
Upon receipt, store it immediately at -20°C or lower for long term storage.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
GMP Human DLL4 Protein, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) captured on Protein A Chip can bind Human NOTCH1 Protein, His Tag, premium grade (Cat. No. NO1-H52H3) with an affinity constant between 1.00 nM - 150 nM as determined in a SPR assay (Biacore 8K) (QC tested).
CD34+ CD45+ hematopoietic cells were seeded on GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) - coated plates and differentiated for 26 days, then flow cytometry was used to detect the expression of T-cell progenitor markers, CD7 and CD5. GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) together with other growth factors could induce the formation of CD7+ and CD7+ CD5+ T-cell progenitors. However, the cells cultured without GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) - coated plates expressed neither CD5 nor CD7.
The Fibronectin fragment, premium grade (Cat. No. FIN-H5113) combined with GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28), GMP Human VCAM-1 Protein, Fc Tag (Cat. No. GMP-VC1H25) coating on the plate could efficiently induce hematopoietic stem cells differentiation to NK cells, with high expression of CD56+ CD3-.
The SPR based assay shows that GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) is stable at 37℃ for 24 hours.
The SPR based assay shows that GMP Human DLL4 Protein, Fc Tag (Cat. No. GMP-DL4H28) is stable after freezing and thawing 3 times.
