How prevalent is HeLa cell contamination still?

  1. May 15, 2012 #1
    This has been a well known problem that has caused millions of dollars of research and thousands of man hours to be wasted. Is HeLa cell contamination still a huge problem that people still don't bother to check for? Are there certain vendors that verify cell lines for this contamination before shipping?

    I'm pretty sure you're supposed to check for that, and whoever is on the receiving end of something should check for it too. Although I'm thinking a lot of people don't bother checking. One of my professors said they had an issue once.
