Hadamard Transform-Charge Detection-Mass Spectrometry
This technology uses a multiplexing approach to online size exclusion chromatography (SEC) coupled with Orbitrap CD-MS. A microcontroller is used to deliver pulsed injections from a large sample loop onto a SEC for online CD-MS analysis. The method produces a series of peaks spaced according to the pseudo-random injection sequence, which are demultiplexed...

A Method for Characterizing Adeno-Associated Virus Capsids with Thermal Unfolding and Mass Spectrometry
This invention describes modulating the temperature of the solution in an electrospray needle prior to charge-detection mass spectrometry (CD/MS) to enable discrimination between the individual stabilities of multiple forms of viral particles that may be present in an AAV preparation. This increased discrimination provides the operator with a unique...

Deconvolution of Charge Detection-Mass Spectrometry Data
This mass spectrometry analysis software and method extends the UniDec Bayesian deconvolution algorithm for application to two-dimensional charge detection-mass data. A 2D plot of m/z versus charge is created from raw data. Smoothing and background subtraction may be used, and deconvolution is applied to remove uncertainty in the charge and the m/z...

Automated Lipid Exchange-Mass Spectrometry System
This invention is an automated label-free method to measure the affinity of membrane proteins for lipids by using conventional small molecule mass spectrometry (MS) to monitor lipid exchange between lipoprotein nanoparticles called nanodiscs. We call this method lipid exchange-mass spectrometry (LX-MS). The concept is that if a membrane protein binds...
