lipase activity detection

Hello,
Does anybody here have experience in detecting lipase activity in the nematode? Neutral lipase assay and acidic lipase activity detection are different. So the protein preparation processes are also various. I referred to related literature but still cannot get information in detail. Would anybody here show me protocols for protein extraction to prepare for neutral and acidic lipases assay? I would appreciate it.
By the way, I consider using Lipase Assay Kit(QuantiChrom Kit, BioAssay Systems, e.g.) and fluorogenic substrate (4-Methylumbelliferyl palmitate) for neutral and acid lipase detection, respectively.

All suggestions are greatly appreciated. :-*
