thanks a lot in advance

here is one :

NaCl 150mM (for osmolarity)
Tris, pH7.2 10 mM (for pH buffer)
triton X-100 1.0% (detergent)
deoxycholate 1% (an other detergent, you should not add it if you want to make some kinase activity analysis on your samples)
EDTA 5 mM (Ca chelator, will inhibit enzymes)
PMSF 1mM (protease inhibitor)
aprotinin, leupeptin, pepstatin 1 ug/mL of each (protease inhibitors)

if you want to analyse phosphorylation state, you should also add phosphatase inhibitors :
Na3VO4 (Na orthovanadate) 1mM
NaF 1 mM
