GMP Monoclonal Anti-Human CD28 Antibody on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of GMP Monoclonal Anti-Human CD28 Antibody(Cat. No. GMP-MC2824) was greater than 95% as determined by SEC-HPLC.
GMP Monoclonal Anti-Human CD28 Antibody (Cat. No. GMP-MC2824) stimulates secretion of IL-2 by PBMC stimulated with 4ng/mL GMP Monoclonal Anti-Human CD3 Antibody (OKT3). The typical EC50 for this effect is 1.382 ng/mL (QC tested).
The activity of GMP Monoclonal Anti-Human CD28 Antibody (Cat. No. GMP-MC2824) was higher than other competing products.
The Cell based assay shows that GMP Monoclonal Anti-Human CD28 Antibody (Cat. No. GMP-MC2824) is stable at 37°C for 7 days.
The Cell based assay shows that GMP Monoclonal Anti-Human CD28 Antibody (Cat. No. GMP-MC2824) is stable after freezing and thawing 3 times.
The Cell based assay shows batch-to-batch consistency between Acro's GMP and PG CD28 Antibody.
