New Products: Imaging MS from Shimadzu, Alzheimer's Markers from Proteome Sciences


Shimadzu this week announced the launch of its Imaging Mass Microscrope, iMScope, which combines optical microscopy and mass spectrometry in one instrument.

The device combines an optical microscope and hybrid ion trap time of flight mass spectrometer, allowing for observation of high resolution morphological images via microscopy and for identification and visualization of specific molecules via mass spec.

The device can visualize molecules with sub-cellular resolution, achieving resolution of 5 µm, and allows for analysis of living cells or tissue samples, the company said.

Proteome Sciences this week launched its Alzheimer's CSF 16-plex assay, a protein biomarker panel for simultaneously measuring 16 protein biomarkers in cerebrospinal fluid.

Using selected-reaction monitoring mass spec, the panel is intended for monitoring disease in Alzheimer's patients and could potentially be used as a diagnostic assay, the company said.
