HeLa cells were the first human cells to be successfully cloned in 1953 by Theodore Puck and Philip I. Marcus at the University of Colorado, Denver. Since that time, HeLa cells have "continually been used for research into cancer, AIDS, the effects of radiation and toxic substances, gene mapping, and countless other scientific pursuits." According to author Rebecca Skloot, by 2009, "more than 60,000 scientific articles had been published about research done on HeLa, and that … WebFor strongly adherent cell lines, trypsin of 2.5 % to 0.25% (10X to 1X power) is used. While the studies which require cell surface protein integrity, lower concentrated (0.05% trypsin) solutions are employed.
