Product news

Eksigent, a developer of advanced low-flow fluid delivery technologies for drug discovery and other life science applications, announces the addition of a NanoLC MALDI Spotting System to its nanoflow chromatography product line.

Featuring the new Ekspot spotter, the new system complements the company’s existing offerings for nanospray mass spectrometry (MS) proteomics analysis. Integration of the Ekspot with the NanoLC provides single-point control from the Eksigent software. The powerful new tool enables the analysis of complex protein and peptide samples with MALDI MS.

“This new capability enables customers to use our powerful NanoLC systems in MALDI applications,” explained Remco van Soest, product manager for Eksigent. “Our NanoLC is already the leading platform for proteomics applications, and many customers have been using our LC with a third-party spotter. Now we can provide them with a solution that is fully integrated and optimized for our NanoLC.”

The Ekspot spotter/fraction collector deposits fractions eluted from the NanoLC onto a MALDI plate, while a built-in pump automatically adds the matrix. High positioning accuracy ensures consistent spotting with maximum resolution. The high-capacity system stores up to sixteen MALDI-targets for high-throughput applications.

By eliminating flow splitting, Eksigent’s proprietary microfluidic technology improves reproducibility and sensitivity and eliminates solvent waste. The NanoLC’s precise microscale flow control runs HPLC gradients at rates as low as 20 nL per minute.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.NanoLCNano LC is a nano scale liquid chromatography technique typically used for proteomic applications. The nano refers to the very low flow rate of the mobile phase in the system. The advantage of nanoLC is its high sensitivity. Often the system is integrated with a mass spectrometer in nano LC-MS or nano LC-MS/MS. When using nanoLC equipment consider column choice, software and accurate and precise flow rate control.MALDI-TOF MSMALDI-TOF mass spectrometers (matrix-assisted laser desorption/ionization time-of-flight) are used for the mass analysis of large molecules, including proteins, DNA, polymers and other macromolecules due to its relatively soft ionization, reducing fragmentation whilst allowing fast data acquisition. Tandem mass analyzers such as TOF/TOF systems can be used to increase resolution and sensitivity of your analysis.
