Product Specific Information
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.
701080 was successfully to detect IL-2 in Flow and ELISA application.
Background/Target Information
IL-2 is a 15 kDa cytokine which is produced by immature CD4 Th precursor and Th0 cells as well as some Th1 cells of the immune system. IL-2 plays an important role as a growth factor, differentiation factor, and regulator of cell death. IL-2 stimulates the proliferation of B cells, augments natural killer cell activity, and inhibits granulocyte macrophage colony formation. The gene for IL-2 is located on chromosome number 14 at the 4q26-q27 locus.
