Can I recharge the column in the Thermo Scientific Phosphoprotein Enrichement kit?
No. The metal and procedure used to charge the columns are proprietary.

Can I reuse or recharge the columns when using the Thermo Scientific Phosphoprotein Enrichment kit?
No. For best results, use the column only one time.

Are samples containing EDTA or reducing agents compatible with the Thermo Scientific Phosphoprotein Enrichment kit?
No. Chelating agents such as EDTA and EGTA will cause metal to leach from the column and hence, reduce binding. Reducing agents such as DTT, 2-mercaptoethanol and TCEP also reduce binding to the column. Remove incompatible substances from the sample by desalting before applying to the column.

Do I need phosphatase inhibitors when using the Thermo Scientific Phosphoprotein Enrichment kit?
Phosphatase and protease inhibitors are not required. If desired, add inhibitors to the Lysis/Binding/Wash Buffer as indicated in the product instructions.

What other type of lysis buffer can I use with the Thermo Scientific Phosphoprotein Enrichment kit?
You can use RIPA buffer to lyse cells; however, dilute the lysate with the Lysis/Binding/Wash Buffer included in the kit for compatibility with the column.
