Intact protein mass analysis 0-50 kDa

Molecular Weight Determination by MALDI MS

Does your protein or peptide weigh below 50 kDA? Then we use MALDI-MS analysis to determine the intact mass weight.

You can use the service to

  • Compare samples – for example batch to batch variation.
  • Determine the purity of your sample.
  • Look for modification such as glycosylations, acetylations, oxidations, etc.
  • Compare with theoretical Mw.

The accuracy on this service lies within 50 ppm (+/- 1 Dalton for a 20 kDa protein).

You get results in 4-8 days. The report lays out the data in a way that is easy to read and understand.

What is the advantage of MALDI-MS compared to the ESI-MS?

The main advantage is that the full mass spectrum can be interpreted without any deconvolution step. We use ESI-MS for proteins up to 250 kDa.
