Mass spectrometric analysis provides you with the molecular weight (Mw) of your intact protein. You deliver a liquid or lyophilized sample in microgram quantities.

We provide
Your sample is dissolved and micro purified prior to mass spectrometric analysis. You have the option to have your sample analyzed by:

• MALDI-TOF and/or
• Electrospray (ESI-MS)

MALDI-TOF analysis is perfectly suited for proteins with Mw below 50 kDa.
ESI-MS delivers more accurate data for larger proteins - Mw above 50 kDa. 
 

You receive
Results are delivered in a detailed and easy to understand report (request sample report) in PDF format containing:

• The MS spectrum and
• Table of molecular weights determined
