W19046A_SparkViolet423_IL2_Antibody_080423
Human peripheral blood lymphocytes were stimulated with Cell Activation Cocktail (with Brefeldin A) (Cat. No. 423303 and 423304) for 6 hours, surface stained with anti-human CD3 APC, and then treated with the Cyto-Fast™ Fix/Perm Buffer Set (Cat. No. 426803). Cells were then stained with anti-human IL-2 (clone W19046A) Spark Violet™ 423 (left) or left unstained (right).
