Theoretically unlimited molecular weight range.

Only two peaks of one protein required, extremly robust.

Highly accurate calculation of molecular weights of proteins, even from low resolution data.

No raw data and peak intesities required, therefore suitable to re-evaluate "historical" data Algorithm based on standard deviation optimization (scatter minimization).However, even if ESI-MS data of most of the naturally ocurring proteins can be measured, the availability of data evaluation software for such ESI protein spectra with low resolution is quite limited. Ion trap devices like the Agilent MSD/XCT ultra or the Bruker HCT ultra are typical representatives. BackgroundĮlectrospray ionization (ESI) mass spectrometry (MS) devices with relatively low resolution are widely used for proteomics and metabolomics. * the example m/z values correspond to the active form of alpha-chymotrypsin from bovine pancreas, with five disulfide (S-S) bonds and attachment of TN (reported in RCM, 2010).

This is the PHP based online version of ESIprot.Īt least m/z 1 and m/z 2 must be provided ESIprot Online enables the charge state determination and molecular weight calculation for low resolution electrospray ionization (ESI) mass spectrometry (MS) data of proteins.
