Figure 2.
Shown is the wash and dry station of the SpotBot® 2 Protein Edition Microarrayer, with the wash port (left) and the drying port (right). The printhead containing 4 Stealth Pins is fully inserted into the dry station in this photograph such that the collars rise above the top surface of the printhead by about 1.0 mm. Customers can also use 946 Pins with extended collars for ease-of-handling and greater printing precision.  A forced air stream generated by the SpotBot® 2 Protein Edition Microarrayer Air Compressor dries each pin independently, essentially eliminating sample carry-over.  Cross-contamination can be further reduced further by using the Megasonic Wash Station option, a favorite of protein microarray researchers.

microarray-samples
Figure 3.
Shown is theSpotBot® 2 Protein Edition Microarrayer in the protein sample loading position. After the wash/dry step, the 4-pin Printhead moves over the first loading position in the 384-well microplate, lowers to the bottom of the plate, and pauses for 3 seconds allowing the protein samples to load into the pin tips by capillary action.  Each pin loads 0.2 µl of protein sample using the SMP4 or 946MP4 pin design. The recommended sample volume is 5-10 µl per well in a 384-well microplate and the recommended protein concentration is 0.1-1.0 µg/µl.  The SpotBot® 2 Protein Edition Microarrayer will print an entire 384-well microplate across 14 protein microarray substrates in less than 2 hours.

All samples were printed in quintuplicate at 200-µm center-to-center spacing.  The uniformity of the rows and columns of printed spots reveals the excellent printing performance of the SpotBot® 2 Protein Edition Microarrayer.  The space bar denotes 500 µm in the image.

microarray-humidity
Figure 5. Shown is the Humidification System for adding humidity to the SpotBot® 2 Protein Edition Microarrayer chamber.  An Air Compressor and Humidification Flask power humidification of the internal chamber of the SpotBot® 2 to be controlled within 1%. See Fig. 9 below for the dehumidification apparatus.

Rationale for the SpotBot® 2 Protein Edition “Cold Room”
Proteins have a number of levels of structural organization including primary structure (amino acid sequence, held together by covalent bonding), secondary structure (e.g. coiled-coils and beta-pleated sheets, held together primarily by hydrogen bonding), tertiary structure (overall protein shape, mediated by hydrogen bonding, disulfide bonds, etc.) and quaternary structure (which combines multiple protein subunits using hydrogen and other types of bonds to maintain subunit affinity).  Each one of these levels of organization is required for protein activity, and these levels of organization must be maintained during and after microarray printing for successful protein microarray experimentation. In addition, intact epitope structure is a requirement for antibody binding and therefore antigen and antibody microarrays. Hydrogen bonding, a key force in maintaining protein folding, has a temperature-dependant component. Temperature-dependant changes in hydrogen bonding can result in protein denaturation and functional inactivation. This is easily observed when a protein source such as an egg white is heated to high temperatures during cooking. This same effect happens at lower temperatures. The rate of protein denaturation doubles every 5-10°C. This helps explain why proteins maintain their properly folded conformations much longer in the cooled SpotBot® 2 Protein Edition Microarrayer chamber versus traditional microarrayers. Another key factor that diminishes protein integrity is bacterial and fungal contamination.  The doubling time of microbes is greatly reduced at lower temperatures, which is yet another advantage of the cooled SpotBot® 2 Protein Edition Microarrayer chamber.  The optimal temperature for most proteins is 4-10°C. For the last one hundred years, protein biochemistry has been performed in the cold room.  Now, ArrayIt® brings the cold room to your desktop.

A total of 24 microarrays per substrate were printed using the Multiple Microarray Format SpoCLe Generator version 1.1.02, which can be downloaded at http://spotsupport.com.

microarray-testing
Figure 7. 
Multiple Microarray Format SpoCLe Generator version 1.1.02 allows the printing of multiple microarrays per substrate with SpotBot 2 Personal Microarrayers (see Fig. 6). Shown is a screenshot of the software interface. The user selects the number of microarrays or “well pattern”, spot spacing in microns, print offsets in millimeters, and subgrid dimensions as columns and rows.  The software then generates a graphic showing how the printed microarrays (orange icons) will appear on the substrates.  The Multiple Microarray Format SpoCLe Generator version 1.1.02 can be downloaded at http://spotsupport.com.

peristaltic-pump
Figure 8.
Shown is a photograph of the Peristaltic Pump used on SpotBot®2 Personal Microarrayers. Tubing colors should be configured as shown. The speed dial should be set to the right (CW, clockwise setting) for correct buffer flow into the Wash Station.  Pumps are either 12 rpm or 100 rpm as designated on the back of the instrument under “speed”.  A proper buffer flow rate of 1.0 ml/min into the SpotBot®2 Wash Station is achieved using dial setting 8 (12 rpm pump) or dial setting 1 (100 rpm pump, shown here). Tubing connections (not shown) should be green-green, blue-blue, yellow-yellow, and white-white as designated on the tubing ends and hardware: green-green = Peristaltic Pump intake to Wash Buffer Reservoir; blue-blue = Peristaltic Pump intake to Wash Station outlet; white-white = Peristaltic Pump outlet to Wash Station intake; yellow-yellow = Peristaltic Pump outlet to Wash Waste Container.

microarray_dessicant
Figure 9. Shown is the Dehumidification Apparatus attached to the  correct port on the SpotBot® 2 Protein Edition Personal  Microarrayer. The Air Compressor (orange) pushes air through a user-controlled valve and into the dessicant tube. De-humidified air is then filtered (green filter) to remove particulate matter, and propelled under pressure into the SpotBot® 2 instrument. The Dehumidification Apparatus prevents excessive humidity from accumulating when the instrument platen is cooled below ambient temperature. Humidity can be held within 1% of the desired level. The Humidification Apparatus (see Fig. 5) is ported onto the same fitting as the Dehumidification Apparatus.

The translucent wash buffer reservoir, orange air compressor for the dry station, silver peristaltic pump for the wash station, silver megasonic power supply and humidification system including the orange air compressor, humidification reservoir and gray valve are shown correctly configured behind the instrument. The modular and compact accessories improve system utility and performance and simplify maintenance and repair. Inside the instrument, the microplate, L-bracket and temperature/humidity pen are visible. The SpotBot®2 Protein Edition Microarrayer is configured similarly except that the humidification is replaced by dehumidification (see Figure 9) and a chilller bath is added for deck cooling.

Figure 11. Shown is a photograph of the SpotBot®2 Personal Microarrayer including the accessories. The translucent wash buffer reservoir, orange air compressor for the dry station, silver peristaltic pump for the wash station, silver megasonic power supply and humidification system including the orange air compressor and humidification reservoir are shown correctly configured behind the instrument. The COM cable, power supply, dry station fitting (red), wash buffer fitting (white), waste buffer outtake (blue), and humidification tubing are shown correctly attached to the back of the instrument. The modular and compact accessories design improves system utility and performance and simplifies maintenance and repair. The SpotBot®2 Protein Edition Microarrayer is configured similarly except that the humidification is replaced by dehumidification (see Figure 9) and a chilller bath is added for deck cooling.

Figure 12. SpotBot®2 Microplate Printing. SpotBot®2 Protein Edition Personal Microarrayers enable microarray printing into 96-well microplates (shown) and 384-well microplates, as well as onto microplate-sized glass substrates using the standard SpotBot®2 Protein Edition components and Well Plate Printing Spocle Generator v2.0.2 software running on SpotApp v3.5.7. Microplate printing software is downloadable on the SpotSupport web site. Microplate printing requires the Microplate L-Bracket Locator (Cat. MLS) to hold the microplate in position during printing, and utilizes two pre-print substrates as shown here. System calibration is required prior to printing. Please do not attempt microplate printing prior to system calibration.
