Now at LP3: absolute molecular weight determination of proteins

Typical data collected using the OMNISEC, in form of chromatograms and tables.

LP3 extends its portfolio of machines available for biophysical analysis by welcoming the OMNISEC system from Malvern Panalytical.

Thanks to a grant from Olle Engkvisits foundation to Prof. Anders Malmström (Experimental Medical Sciences, Lund University), we now host a state of the art multi-detection size exclusion chromatography (SEC) system: OMNISEC. The OMNISEC system is now available to users.

SEC is an essential technique for the characterization of proteins. A series of three different detectors coupled to the SEC: light scattering, refractometer and viscometer, then deliver a powerful information panel about your sample.

The OMNISEC requires only 20 to 100 µg of protein sample per injection for measurement of absolute molecular weight, molecular size and sample composition. The temperature-controlled autosampler allows us to load multiple samples per run. NB: our system does not currently include the SEC-MALS module
