For those of you who wanted to see the responses to the cell culture
"clumping" query, these are some of the responses I received. Thank you to
everyone who helped me out.
If you filter your cells through an 80 micron mesh and then "scoop" some
cells (not the clumps) with a spatula into a new flask with medium, you
should be able to get rid of the clumps. The media I used can be found here:
If your concern is simply for ease of examination under the
microscope, it may be worth transferring your cells for examination
into 0.1M EDTA (pH 8.0) for an hour or two before you wish to look at them.
The EDTA chelates the calcium from the cell walls, and loosens the
If the clumping is preventing you from getting accurate cell counts
for estimating culture density, this may not be of much help.

Diluting the cells in water and vigorously vortexing them can
partially disassociate clumps. Additionally, pellet the cells and
resuspend them well in a sterile 0.1% agar solution. You might also
trying to growing the cultures in media containing 0.1% agar. This
concentration of agar is a liquid, not a solid.
