The Kei-α1 antibody reacts with the rabbit homolog of CD25, the interleukin-2 receptor alpha chain (IL-2Rα). mAb Kei-α1 recognizes specifically IL-2Rα and neither the IL-2R ß chain (CD122) nor the 25- kDa protein component of the rabbit high-affinity IL-2R complex. Based on flow cytometric analysis, fewer than 1 % of resting peripheral blood T and B cells have been found to stain with Kei-α1, while a majority of PHA blasts show intense staining with Kei-α1. The HTLV-1-transformed rabbit cell lines, F648b and YR-1 both also show intense staining with Kei-α1. mAb Kei-α1 has been reported to block both high-and low-affinity IL-2 binding and also cell proliferation of rabbit PHA blasts induced by picomolar concentrations of IL-2.
