In our lab we have been using flow cytometry for almost 10 years to sort
phytoplankton either directly from natural communities or from cultures and
we obtained viable cells in most cases. Our problem is rather to get pure
cultures after sorting because when we sorted from mixtures of algae we
often failed to recover pure cultures from only one type.
The following recommendations apply.
- Sterilize your instrument before sorting
- If you deal with marine algae, use 0.2 um filtered sea water as sheath fluid
- Rince very thoroughly so that no trace of bleach (if bleach is used for
routine cleaning) is left.
- If you are using an instrument with a big laser, lower the laser power as
much as you can (below 100 mW).
