The Quansys Array is printed on a 96-well plate. Stringent quality assurance
measures are applied before each plate is approved for use. We have applied
multiple steps to quality assure each plate.
First, a visual inspection of the plate, second a fluorescein image,
and finally a complete assay is run on one plate from each lot and compared
to our thorough criterion.
The first step of quality assurance is a visual inspection of a plate.
After the plates are printed in a Class 1000 clean room, each plate is
visually inspected for any obvious defects which could include spot deformation,
dust, or other particles. All plates that do not pass the visual inspection
are discarded at this time.
The second step is capturing an fluorescent image. Fluorescent dye is
mixed with the antibodies before it is printed on the plate. This dye
has no adverse effects to the antibody or function of the array. This
patent-pending technology allows us to ensure proper spot deposition.
The image is captured with a CCD gel doc camera system using an UV light
and appropriate lenses. The image is examined for spot deformities, extra
spots, and airborne contaminants. All plates that do not pass this step
are discarded.
Figure 1 shows the fluorescent dye image from a plate that passed QA.
All the spots are of relative size and brightness, there are no blurred
spots or particulates on the plate. Figure 2 shows a fluorescent dye image
that did not pass QA testing. There are a number of artifacts on the plate
due to airborne dust or fibers and a few deformed spots.
Quansys Biosciences is committed to providing high quality research
products. We have implemented our patent-pending quality assurance technology
along with our ISO 9001/2000 registration to ensure each array kit is
of the highest quality. To view the fluorescent dye image for your specific
plate, go to the QA plate image database. Each plate has a bar code on
the side of it; simply type in this code and click 'Get Image.'
