This product is stable after storage at:
Human IL-21 Superior Stable Mutant Protein, premium grade on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
The purity of Human IL-21 Superior Stable Mutant Protein, premium grade (Cat. No. IL1-H5113) was greater than 95% as determined by SEC-HPLC.
Recombinant Human IL-21 stability studies in the T culture medium. Human IL-21 Superior Stable Mutant Protein, premium grade (Cat. No. IL1-H5113) or wild-type (WT) Human IL-21 Protein, premium grade (Cat. No. IL1-H5114), or Company M Human IL-21 Protein were added in the T cell medium at an initial concentration of 22 ng/mL, respectively. IL-21 concentration tested with resDetect™ Human Interleukin-21 (IL-21) ELISA Kit (Cat. No. CRS-A010). Following 3 days of treatment at 37°C, Recombinant Human IL-21 Superior Stable Mutant Protein retained the concentration 70%, demonstrating its enhanced thermal stability. In contrast, the WT Recombinant Human IL-21 Protein exhibited significant concentration loss, indicating inferior thermal stability.
Human IL-21 Superior Stable Mutant Protein, premium grade (Cat. No. IL1-H5113) stimulates secretion of IFN-γ by NK-92 human natural killer lymphoma cells stimulated with Human IL-15, premium grade (Cat. No. IL5-H4117), The specific activity of Human IL-21 Superior Stable Mutant Protein, premium grade is > 4.00 x 10^5 U/mg (QC tested).
Immobilized Human IL-21 Superior Stable Mutant Protein, premium grade (Cat. No. IL1-H5113) at 5 μg/mL (100 μL/well) can bind Human IL-21 R, Fc Tag with a linear range of 0.5-8 ng/mL (QC tested).
