Several hundred thousand samples in a single run
Analytik Jena brings extensive automation and liquid handling experience to automated sample preparation for uHTS applications supplying a walk away automation solution for MALDI-TOF-MS able to handle several hundred thousand samples in a single run.
An ultra-high-throughput automation solution
With matrix-assisted laser desorption/ionization time-of-flight MS (MALDI-TOF-MS) mass spectrometry is now available for high throughput screening (HTS) e.g., in drug discovery. The Bruker Rapiflex MALDI-TOF-MS is rapidly becoming the instrument of choice for HTS and ultra HTS (uHTS) in pharma, academia and the commercially focused contract environment. It is the fastest mass spectrometer on the market enabling collection of real-time data in high throughput high density when automated into a robotic sample preparation system. Analytik Jena supplies all application demands for a reliable MALDI automation, from a simple workstation to a complex integration. The solution enables 1536 samples to be spotted onto a MALDI target plate in less than 10 minutes facilitating continuous sample reads in a screening environment.
Small assay volume and homogenous spot generation for MALDI
The liquid handling demands for sample preparation in high-density are diverse. The robust and precise CyBio Well vario 1536 pipettor ensures sample integrity and result reproducibility in either 384‑ or 1536-well formats by spotting an entire target plate in a single transfer.
MALDI sample clean up enables the reduction of salt interferences
On-target washing enhances detection capabilities of target molecules in complex assay buffers and thus accelerates assay development. The desalting function of on-target-washing significantly improves both the assay conditions and the measurement results. The CyBio Well vario Head 1536/8μl can complete on target-washing for 1536 samples in less than 60 s.
Active Drying provides extremely homogenous spot shapes
The "Active Dryer" is an important element of the automation for MALDI-TOF-MS sample preparation. By enabling controlled crystallization conditions, the active dryer allows faster sample preparation and creation of extremely homogeneous sample spots.
Smart accessories perfectly supply the needs of MALDI sample preparation
To avoid sample carry-over, tip washing between spotting of assays plates is essential. The CyBio Well vario offers automated and optimized tip washing steps in 384- or 1536-well format. Thanks to highly efficient washing stations, no cross-contaminations can be detected following only three washing cycles.
Modular and customized automation solutions
Based on a modular system, the degree of automation can be freely configured by the customer. In addition to high-quality liquid handling equipment, Analytik Jena also offers fully automated automation solutions tailored to the respective customer needs.
Software is the key element for automation systems. Our powerful and scalable software packages allow detailed control of all components for MALDI-TOF sample preparation as well as easy handling of the complex scheduling tasks.Thanks to its sophisticated software and scheduling concept the HTS CyBio automation solution for MALDI-TOF-MS sample preparation is capable of preparing the specific sample plates within the same time as the mass spectrometer can measure them (< 10 min). This allows the screening of one million samples in less than five days.
