GMP Human IL-21 Protein 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 IL-21 Protein (Cat. No. GMP-L21H25) stimulates secretion of IFN-γ by NK-92 human natural killer lymphoma cells stimulated with 10 ng/mL GMP Human IL-15 Protein (Cat. No. GMP-L15H13). The specific activity of GMP Human IL-21 Protein (Cat. No. GMP-L21H25) is > 1.00×10^5 U/mg (QC tested).
The Cell based assay shows that GMP Human IL-21 Protein (Cat. No. GMP-L21H25) is stable at 37°C for 24 hours.
The Cell based assay shows that GMP Human IL-21 Protein (Cat. No. GMP-L21H25) is stable after freezing and thawing 3 times.
The Cell based assay shows that GMP Human IL-21 Protein (Cat. No. GMP-L21H25) is stable at 4°C for 6 months.
The Cell based assay shows batch-to-batch consistency between Acro's GMP and PG IL-21.
