CAROLINA GONZALEZ: we use an extraction method for multiplataform analyses. We add MeOH:H2O 50% (1mg tissue:10uL solvent) for Mouse face Brain homogenization using a TissueLyser. Then, we mix 100uL of brain homogenate with 320uL MeOH + 80uL MTBE (for lipids) DOI: 10.1021/acs.jproteome.8b00816.
WENYUN LU: For tissue samples our preferred extraction method is first grind into powder then add 40:40:20 methanol:acetonitrile:h2o+0.5% formic acid then neutralize with 15% NH4 HCO3 followed by two rounds of centrifugation. https://doi.org/10.1089/ars.2017.7014
