Does your DPBS contain magnesium? Some do, some don't.

DNAse only works in the presence of Mg++. We use DNAse I, 300 mcg/ml,
(60,000 Dornase U/mg) to break all sorts of cell clumps. I can't
remember it failing (but this may be a reflection on the biology of my
memory, as much as the biology of cell clumps).

Can anybody help me with a cell suspension solution that will inhibit
cell clumping. We disaggregate lymph node tissue for routine flow but
have heaps of trouble with cell clumping. We have tried Mg and Ca
RPMI, also DPBS with DNAse to no avail. We keep blocking up the probe
of the XL which is a bit of a bother.

Willing to try anything!!!!!!!
