Process from ordering to final analysis

After ordering and reaching the samples, they are processed immediately. For this, the amino acids are derivatized with the self-produced pure fluorescent compound, 6-aminoquinolyl-N-hydroxy-succinimidylcarbamate (AQC). Prepared samples are then loaded on an ultra-pressure reversed-phase chromatography (UPLC). The desired amino acids are separated and detected. The analysis is completed within 6 minutes. The chemical reaction of the derivatization can be monitored in the "chemical process". The quality and reliability of detected amino acids is checked by means of individual standards with a defined concentration and the final concentration of each amino acids is determined.

We also offer a hydroponic cultivation system for growing small plantlets such as Arabidopsis under sterile and controlled environmental conditions. The system consists of a piece of stainless-steel wire cloth (125 μm mesh size) that is fixed between 2 flat rings and held in place by 3 legs, placed in a commercially-available glass jar, and covered by the original glass lid or alternatively by a sheet of sterilized cellophane. Sterilized seeds can be distributed evenly across the mesh piece with the size, which allows root growth and keeps the seeds in place. After few weeks of cultivation, shoot and root tissues can be easily harvested separately for metabolite and/or nutrient measurements without mechanical damage.

 *Price for each unit is 25 Euro exclusive of 19 % VAT.
