in fact I want using gill and liver cells.
Hey,
if you are looking for a protocol, you may start here:
http://www.ncbi.nlm.nih.gov/pubmed/11386733
Here, the cells are taken into culture before exposure, but you might skip that and expose the fish directly.
As a start for preparation of cell suspensions from tissues, maybe take a look at that one, too:
http://www.ncbi.nlm.nih.gov/pubmed/16916029
Hope I could help you getting started.
Please find the protocol
for example in gill tissue, considering number of lamella(each treatment 500 lamella).

i mean are chemical compounds of lysis buffer able to damage, probably. lysis solution include: (2.5 M NaCl, 0.1 M EDTA, 10 mM Tris, 1% Triton X-100, 9% DMSO, pH 10)
