For Micro-array Preparation

Oligonucleotide re-arraying

Micro-arraying has become a technique of choice for the study of gene expression. Re-Arrangement of even just a few hundred oligonucleotides by hand is not only tedious but highly prone to non-traceable errors. This is typically a task of choice for the MICROLAB® STAR because it requires precision pipetting and traceability, as well as flexibility. The MICROLAB® STAR can operate as part of a micro-array platform for spotting services for various micro-array applications, such as transcriptomics or genotyping for various model organisms.

Prior to micro-array spotting, libraries of oligonucleotides have to be rearranged and diluted according to a unique pattern to prepare 384-well microtiter plates ready to be used by the spotter.  Dilution factors and patterns vary from one spotting project to another. These parameters can be entered into the system by a worklist. The high pipetting precision of the MICROLAB® STAR ensures repeatability in the dilutions.
