You may treat the cells with lysozyme (0.5 mg/ml) for a couple of hours.
Then freeze the cells and de-freze several times. Some DNAase could be
useful to advoid excessive viscosity due to chromosomal DNA. This is a
protocol from Pharmacia, used for GST protein extraction, so must be OK.
E-mail me if you cannot find it in the Pharmacia webpage.
