GMP Human IL-4 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-4 Protein (Cat. No. GMP-L04H26) stimulates proliferation of TF-1 human erythroleukemic cell line. The specific activity of GMP Human IL-4 Protein is > 1.20×10^7 IU/mg, which is calibrated against human IL-4 WHO International Standard (NIBSC code: 88/656) (QC tested).
The activity of GMP Human IL-4 Protein (Cat. No. GMP-L04H26) was higher than other competing products.
The Cell based assay shows that GMP Human IL-4 Protein (Cat. No. GMP-L04H26) is stable at 37℃ for 24 hours.
The Cell based assay shows that GMP Human IL-4 Protein (Cat. No. GMP-L04H26) is stable at 4℃ for 180 days.
The Cell based assay shows that GMP Human IL-4 Protein (Cat. No. GMP-L04H26) is stable after freezing and thawing 3 times.
The Cell based assay shows batch-to-batch consistency between Acro's GMP and PG IL-4.
