Due to the mutation, the seeds I am going to use for EMS mutagenesis tend to float on the solution. Is there any detergents possibly I could use prevent the floating?
We pack the seeds in a small bag (made e.g. from miracloth or something similar) and add some small metal piece (e.g. a screw) so that the whole bag and seeds are fully soaked in the solution. We also mix the solution on the magnetic stirrer.
