Metabolism by flow

I do not know of any methods that will allow quantitation of lactate 
levels in cells via flow. The problem, in part, is that the rate of 
lactate efflux, once produced in the cells, is very rapid and thus, it 
is difficult to measure intracellular levels accurately.  Sigma 
Diagnostic sells a lactate measurement kit which allow for the 
measurement of lactate secreted into the tissue culture medium.  We use 
NMR to monitor 13C incorporation into lactate from [1-13C]glucose in B
