Title: Normalization using cell protein content
Post by: panda4177 on April 20, 2021, 08:25:02 AM
Dear Community,
I am working on a cell-based metabolomic project. Does anyone know how to normalize the data using protein content in MS-DIAL?
Thank you!
Pan

Hello Pan,

do you have additionally an internal standard in your samples?

If yes: IS normalization in MS Dial, then take the alignment sheet and divide your samples by the corresponding protein amount.

If not: take the alignment sheet and divide your samples by the corresponding protein amount

You can do a TIC / mTIC normalization, but I'm not very confinced it has a lot of benifits.

All the best,
Martin
