Microarry Print Head

Application:  Microarrays are used to measure gene, protein and cell activity in response to stimuli or to identify and study mis-stitches in genetic sequences.  Although microarrays are made by several methods, one of the most popular is to “spot” them on microscope slides.  Spotting uses arrays of fine tipped pins to dip into wells containing capture molecules and then transfer the capture molecules to the slides via surface tension forces.  Once the pins come into contact with slide, they generate a series of capture molecule spots.

Features:  This machined set of Macor® print head plates have hole position accuracies to within 10um.
