Product Specific Information
This antibody is predicted to react with non-human primate, mouse and rat based on sequence homology.
ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Background/Target Information
IL21 is a 15 kDa protein and is a potent factor for naive B cells. IL21 and its receptor IL21R are connected to natural killer cell expansion and regulate lymphocyte function. IL21 is known to inhibit dendritic cell activation and maturation. IL21 and IL21R are known to activate JAK/STAT pathway and have been connected to cancer and autoimmunity. IL21 plays an important role in immunoglobulin production.
