clumping of MEFs in suspension

MEF= Mouse embryo fibroblasts. They don't clump. Check out for
mycoplasma contamination. Some mutant cells show stress effects and
clump. If they are clumped in huge clumps and floating, then they are
dead. Throw them away. Check for viability with trypan blue exclusion
Best of luck

What is an MEF?
Abbreviations and acronyms often have many meanings. Really helps to
give good info if you want good feedback.

Well, regardless of what MEF means, that is an interesting question.
You will find out by seeing if it is reproducible, with proper
controls. Perhaps a solution was not correct this time, or perhaps you
do have a novel phenotype of your mutations.
