The PamStation®12 platform is composed of:
- Peptide microarrays (PamChip® arrays)
- Workstation (PamStation® hardware)
- Data analysis & interpretation package (BioNavigator)
Principle
PamGene’s flow-through arrays technology is based on measurement of i) peptide phosphorylation by protein kinases or ii) nuclear receptor - ligand - coregulator interaction.
The peptides are immobilized on a dedicated microarray and detection uses fluorescently labelled antibodies. These microarrays consist of a highly porous ceramic membrane on which 144 or 154 peptide substrates are immobilized. On each PamChip®4, four arrays are combined.
The assay detects kinase activity or nuclear receptor – coregulator interaction mostly in kinetic assays over the course of about 1 hour. This is accomplished by an up and down movement of the sample solution through the array, giving the kinases or nuclear receptors, maximal opportunity to phosphorylate or bind the peptides on each array When the solution is underneath the array the CCD camera in the workstations will take an image of each array. The incubation, washing, dispensing of reagents and imaging of the PamChip® arrays is done in a fully automated workstation: the PamStation®12. The PamStation®12 takes typically 15 images during the incubation of one hour. The data workflow consisting of image quantification, quality control, statistical analysis, visualization and interpretation is performed using the BioNavigator software.
