Phospho-HER2/ErbB2 (Tyr1248), Cell Signaling Technology, 2247

This antibody did not work very well for me. Little to no signal was observed at ~190kDa marker in wildtype cortical neurons from mice.

Dilution 1:1000

Lysis buffer:

• 20 mM MOPS
• 2 mM EGTA (to bind calcium);
• 5 mM EDTA (to bind magnesium and manganese);
• 50 mM sodium fluoride (to inhibit protein-serine phosphatases);
• 60 mM β-glycerophosphate, pH 7.2 (to inhibit protein-serine phosphatases);
• 25 mM sodium pyrophosphate (to inhibit protein-serine phosphatases);
• 2.5 mM sodium orthovanadate (to inhibit protein-tyrosine phosphatases);
• 50nM phenylarsine oxide (to inhibit protein-tyrosine phosphatases);
• 1% Triton X-100
• 0.05% sodium dodecylsulphate (SDS)
cOmplete™ Protease Inhibitor and DTT added before use.
