Labelling proteins in plant protoplasts

Does anyone have any suggestions for increaseing the effeciency of labeling of 
proteins in plant protoplasts?  I am trying to label a transiently expressed 
protein for the purpose of measuring its half-life.   Currently, I am pulsing 
the cells with 35-S methionine/cysteine (100-200 micro CI) in a volume of 
0.5ml.   The level of incorporation is very low following immunoprecipitation. 
 Are there any special conditions which will increase the amount of label 
taken up by the protoplasts?
