NanoPrint™ Protein systems enable the manufacture of microarrays utilizing ArrayIt® 192Professional946 and Stealth Style Micro Spotting Pins. The NanoPrint™ Protein uses superior linear drive motion control technology and proprietary Warp1 controllers, and is compatible with all standard microarray surfaces made by ArrayIt® and other glass substrate slide open platform vendors. Systems are easily configured to print onto different types of surfaces including 96-well plates, plate-sized glass, and proprietary cartridges and cassettes by taking advantage of flexible and modular deck configurations and an easy to use software interface.  The Microarray Manager Software combines unparalleled power and simplicity in a graphical user interface.  Click here for a NanoPrint™ Protein Microarray Manager Software tutorial.

Rationale for the NanoPrint™ Protein
A starter pack of consumables to get you started printing your sensitive samples immediately includes Microarray Microplates, SuperEpoxy Substrates, SuperProtein Substrates, Protein Printing Buffer, and BlockIt Blocking Buffer.

  • Proteins have a number of levels of organization. This includes the primary structure, (amino acid sequence, held together by covalent bonding), the secondary structure (structures such as the beta-pleated sheets and that are held together primarily by hydrogen bonding), the tertiary structure (held together by hydrogen bonding and disulfide bonds) and the quaternary structure (which combines multiple amino acid sequences together by hydrogen, disulfide and other bonding).
  • Each one of these levels of organization is required for an active protein and required to print high quality protein microarrays that can detect protein interactions. In addition, intact epitope structure is a requirement for antibody binding.
  • Hydrogen bonding, the force that maintains the correct folding of proteins, has temperature-dependant labiality. This temperature-dependant change in structure results in protein denaturation and inactivation and destruction of proteins. For every 10 degrees Celsius, the rate of denaturation doubles.
  • The optimal temperature for proteins in the liquid phase is 4ºC. For the last 50 years, protein biochemistry has been performed in the cold room. The Protein Edition NanoPrint™ reduces or eliminates the requirement to work in the cold while maintaining protein structure.
  • Another key factor that affects protein integrity is microbial contamination (bacteria and fungi). The metabolic rate of microbes is greatly reduced in the cold, which reduces microbial doubling time and sample degradation.

A 48-pin NanoPrint Protein printhead loaded with 48 946 Micro Spotting Pins is printing location 8 on the deck. The modular deck design and platen cassettes allow users to easily switch between glass substrates, microplates, wafers and other types of substrates. Click here to view NanoPrint™ 2 videos.

Accessory Control Module (ACM):
The ACM unit provides computer control for the wash/dry, humidity, and ultrasonication stations on the deck of the NanoPrint™ 2 Protein. The ACM unit fits neatly beneath the laboratory bench or under the optional anti-vibration table available with the system. The ACM is extremely quiet and operates only as needed by the system. Humidity is maintained in a user-specified manner of ±1%. Wash buffers are stored in carboys in front of the ACM.

NanoPrint™ 2 Protein Pin Cleaning Module:
NanoPrint™ Protein microarrayers are each equipped with a station that provides pin washing, drying and sonication of 1-48 pins. The sonicator is automatically filled and emptied during the print run in a completely automated manner. Systems sensors prevent splashing and overflowing for pin and deck safety. Drying is accomplished by vacuum using a quiet but powerful ACM-controlled function.  The Pin Cleaning Module is rugged, durable and easy to maintain.

NanoPrint™ 2 Protein ACM Connectivity:
Easy connectivity between the ACM and the robot and accurate sensing of the humidity inside the chamber assures that proper humidity levels are achieved and maintained during the entire duration of each print run. Dehumidification is an option available at an extra cost and is highly recommended for users who wish to operate their systems in humid environments. The humidification and dehumidification systems are triggered by sensors that automatically maintain the levels set by the user.

NanoPrint™ 2 Protein Humidity Sensing:
Accurate sensing of the humidity inside the chamber assures that proper humidity levels are achieved and maintained during the entire duration of each print run. Dehumidification is an option available at an extra cost and is highly recommended for users who wish to operate their systems in humid environments. The humidification and dehumidification systems are triggered by the RH sensor that automatically maintain the levels set by the user.

NanoPrint™ 2 Protein Microplate Peltier Cooling:
NanoPrint™ Protein systems offer sophisticated microplate cooling via Peltier as an affordable and highly recommended option for users wishing to minimize sample evaporation during printing. Microplate cooling is also highly recommended for protein microarray applications to minimize protein denaturation and microbial growth in recombinant protein samples. The Peltier module fits directly beneath the microplate for highly efficient cooling while maintaining a low deck profile.

NanoPrint™ 2 Protein Software:
The extraordinary and highly intuitive graphical user interface provides users with software writing speed, power and flexibility. Shown here is a screen shot of  the interstitial printing software command that automatically directs the robot to deposit the printed spots into a “orange packing” configuration for dramatically increased microarray printing density.

48 and 192 Pin Configurations are now available. 192 Pin configuration allows the user to run from 1 to 192 pins at 2.25 mm center to center spacing to pickup samples from 1536 well plates. Standard deliverable is 48 Pins at 4.5mm centers for use with 384 well plates (96 well plates can also be configured).  NanoPrint™ 2 software and unique Pin and Printhead design allows the end user to setup the pin tool any way that they like. Multiplex array processing systems, plates, biochips micro fluidics, and cartridges can all be easily configured.

Superior Z-Axis Resolution for Optimum Spot Morphology:
The Z-axis encoder on the NanoPrint™ 2 Protein reads at 250-nanometer resolution. Unlike belt and stepper motor driven Z-axis motion control, the NanoPrint™ 2 Protein offers highly precise resolution, repeatability and computer control over the speed and acceleration settings to ensure optimal printing onto any surface using our patented contact printing technology. Optimal parameters are set at the factory but can be easily changed by the user for printing onto many different surfaces.

Figure 8.
 Shown is the point of a Professional Series 3 (Pro3) microarray printing pin. Samples load into the pin uptake channel by capillary action, and direct contact between the sample layer on the pin tip and the glass printing substrate results in the formation of a printed microarray spot. The NanoPrint™ Protein LM60PRO-2 and LM210PRO-2 systems control pin movements in 500 nanometer increments for unsurpassed printing precision at speeds of 48 spots per second. A total of 48 microarray printing pins of any tip size from the professional946 or Stealth series may be used on our NanoPrint™ 2 Protein systems.
