Microarray scanner for microarrays, tissue and cell arrays, and fluorescence studies
Eliminate the inconvenience of waiting to use a scanner in a core facility or your neighbor's lab.
High-performance microarray scanning is now more affordable than ever. Built on our award-winning optical,
electronic and software design, the GenePix® Personal 4100A microarray scanner
(winner of an IBO Design Award)
has all the quality and ease-of-use of more expensive scanners, but in a price range and bench top footprint
that makes it ideal for individual lab use. Achieve your personal best with the GenePix Personal microarray scanner.
How We Do It
Although lower priced, the GenePix Personal microarray scanner has the sensitivity,
throughput, reliability and flexibility that you absolutely require for your
microarray-based research, be it in genomics, proteomics or drug discovery.
The sequential scanning mode incorporated in the GenePix Personal made it possible to reduce the development
and manufacturing cost without sacrificing the superb quality that you've come to expect from us. But don't
just take our word for it - ask your colleagues about the outstanding quality of the industry-leading GenePix
microarray scanner.
Choosing Your GenePix Scanner
The performance and many features of the different GenePix models are similar, so
check the GenePix Scanner Comparison Table
to see the key differences.
Eight-Position Filter Wheel for Flexible Fluorophore Selection
A variety of fluorophores can be used with the GenePix Personal microarray scanner.
Its new optical design incorporates an eight-position emission filter wheel (Figure 1) with
two standard filters for red and green fluorophores. Up to six additional filters can be
installed, providing flexibility to explore alternative dyes (Table 1). The emission filter
is easily selected in GenePix Pro (Figure 2; click for larger image).

Unparalleled and Industry-Leading Ph.D-level Technical Support
Axon Instruments has long been recognized for its outstanding technical and application support, which is included with every Axon product. Our application scientists come from an academic research background with Ph.D. and post-doctoral experience in a field of molecular biology, cell biology or neuroscience and extensive experience with laboratory instrumentation and software. When you call technical support, you're also getting a trained scientist who understands the biological basis of your experiment in addition to the details of Axon's microarray products. Since our founding in 1983, Axon Instruments, Inc. has always provided free technical support for the life of our instruments.
Ultra-low-noise Signal Digitization
Axon Instruments has built its reputation designing ultra-low noise amplifiers and digitizers
for electrophysiology measurements. The GenePix Personal detection system employs a low-noise,
high-sensitivity photomultiplier tube (PMT) to convert photons into an electrical signal,
which is then digitized using Axon's world-leading ultra-low-noise digitizer technology.
High Resolution Imaging for Precise Detail
The GenePix Personal microarray scanner allows the same flexibility for scan resolution as
the GenePix 4000B. Use the 40-micron Preview Scan to locate the array and optimize hardware
settings, and the Data Scan for accurate quantitation. The GenePix Personal has selectable
scanning resolution between 5 and 100 microns for flexibility in a variety of samples.
Resolution of 10 microns is suitable for most nucleic acid microarrays with larger feature
sizes (>100 microns), whereas 5-micron resolution provides more precise quantitation for
smaller features (<100 microns) or for scanning cell or tissue samples. A 5-micron
resolution target illustrating the resolving power of the GenePix Personal is shown in Figure 3.
Real 5-micron imaging resolution Figure 3. Each bar is 5-microns wide separated by 5-micron spacing.
Uniformity
The GenePix Personal microarray scanner was specified and tested for field uniformity using
a proprietary low-bleaching test standard array. The slide was scanned twice; first with
the slide in one orientation ('forward') and then rotated 180° and scanned again
('reverse'). Mean variability of the intensity ratio (forward/reverse) for all features
was 7% and 3.7% (total range) for the red and green channels, respectively.
Repeatability and Calibration
Repeatability, both day-to-day and scanner-to-scanner (for facilities with multiple scanners)
is possible with Axon's scanner calibration slides, which are included with every GenePix
Personal microarray scanner. These calibration slides are optimized for fluorescence with
635 nm and 532 nm excitation, respectively, and exhibit negligible photobleaching. As such,
they can be used on a regular basis to calibrate your microarray scanner for repeatable PMT
performance over long periods of time.
Automatic Laser Power Correction
Laser power is dynamically monitored during scanning to ensure constant signal output. High-quality lasers coupled with exclusive intensity correction circuitry guarantee that all pixels in the image have equal effective exposure.
Dynamic Scan Monitoring
During scanning, GenePix Pro automatically graphs a histogram of the distribution of pixel intensities for whichever part of the image is displayed. The image and the histogram are updated dynamically as scanning proceeds. Both can be used to optimize scanner settings on the fly. GenePix Pro automatically logs all scanning, file saving, and file loading events.
Performance Diagnostics
The status of each major scanner subsystem, such as laser power and scanning motor force and position is monitored and available at all times. The Hardware Diagnostics Report keeps a record of ongoing scanner performance assessments so that you can immediately identify and correct significant changes. GenePix Pro allows you the option to compensate for gradual changes inherent to all lasers and PMTs through an automated Calibrate System function in GenePix Pro. Each GenePix Personal scanner comes with a set of performance calibration standards—simply insert the standard into the slide holder and click "Calibrate" to restore your scanner to factory-set signal output benchmarks.
Automation and Customization
Once you have determined the appropriate settings for a batch of slides, you can use a simple list of checkboxes to direct GenePix Pro to automatically run any steps in the scanning and analysis process. Automation steps include Preview and/or Data scanning, saving images, analyzing data using a saved array template, and saving Results files. The built-in scripting interface gives you even greater control and flexibility for totally customized automation of any GenePix commands from scanning through analysis and reporting. Example scripts provide building blocks for you to create and customize your own reports including scanner control, images, tables, and graphs.
Flexible Scan Parameters
PMT gain is adjustable to maximize signal-to-noise ratio. The GenePix Personal microarray scanner allows user-selectable averaging of multiple scans lines for even greater signal-to-noise ratio on faint samples.
Barcode Reading
GenePix Pro automatically reads barcodes from Preview Scans, Data Scans, and saved images. Barcodes can be included automatically in file names, and are exported with extracted data.
The GenePix Personal microarray scanner is ideally suited for a variety of fluorescence
applications including tissue and biopsy imaging, protein microarrays and biomarker and
diagnostic panels. The following images show the versatility of the GenePix Personal
microarray scanner.

GenePix is fully functional with the Minimum computer requirements. However, satisfactory performance
depends on the size of the files you will generate. The RAM and hard disk configuration is the most
critical. If you plan to scan areas smaller than a full slide, or to scan regularly at 10 µm
resolution, the Minimum requirements will provide satisfactory performance of all GenePix Pro features.
However, if you plan to scan full slides at 5 µm, or if you plan to run other applications
simultaneously, we strongly suggest the Recommended configuration. Computer workstations purchased
from Molecular Devices will meet or exceed the Recommended configuration.
