Molecular Weight Determination

of protein and peptides

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

Accurate MW determination within +/- 2 Da
Analysis report within 2-4 days
Easy to understand reports
MALDI MS analysis of proteins up to 50 kDa

We provide

Your sample is dissolved and micro purified prior to mass spectrometric analysis. MALDI-TOF analysis is good for proteins with Mw below 50 kDa.
Larger proteins are analysed by ESI-MS. This service is offered as Contract Analysis - please contact us for quote.
