Protea's REDIchip™ enables matrix-free small molecule analysis on your MALDI platform.
REDIchips (Resonance-Enhanced Desorption Ionization) are sample target plates with nanopost array (NAPA) surfaces for matrix-free laser desorption ionization of small molecules. This robust alternative to sample analysis by traditional methods requires minimal sample preparation and is suitable for simple and complex mixtures. Using a matrix-free approach, small molecules can be rapidly and quantitatively analyzed producing sensitive, reproducible results. The REDIchip is easily integrated into existing MALDI-MS instrumentation using standard 1" x 3" adaptors, and the high-throughput, 96-target design features generous 2 mm spots for accuracy in sample spotting.
