Join us for this comprehensive masterclass episode as we explore the fascinating world of K562 cells with Dr. Tom Karagiannis, who has worked with these remarkable cells for almost three decades. From his first encounter with them as a young researcher in 1996 during the exciting era of targeted therapy development, Dr. Karagiannis shares both the scientific breakthroughs and practical realities of working with these "weeds" of the lab.
