Bruker Daltonics in conjunction with Eppendorf announced this week the launch of its Prespotted AnchorChip, a disposable MALDI chip designed for use in LC-MALDI proteomics experiments.
The Prespotted Anchor Chip comes in a 384-sample microtitre plate format with 96 calibrant spots, conveniently pre-spotted with matrix. The chip is comparable to non-disposable steel-chips in terms of mass accuracy, the company said.
“The Prespotted AnchorChip all but eliminates any significant risk of memory effects or cross contamination and it makes MALDI sample preparation far more convenient and less error-prone,” said Michael Schubert, vice president of R&D for Bruker Daltonics.
Prespotted AnchorChips are delivered under inert gas in a container that can also be used for sample storage after analysis.
Bruker Daltonics also announced this week the launch of its ultraflex II MALDI-TOF and TOF/TOF mass spectrometer. The new mass spec offers further improvements in sensitivity, resolution and mass accuracy, the company said, allowing for the analysis of post-translational modifications and top-down protein determination.
