The Topaz System
The Topaz protein crystallization system was originally launched in 2003. Fluidigm has ended new system sales for the following TOPAZ system components:

  • TOPAZ AutoInspeX II Workstation (TPZ-AIXII)
  • TOPAZ IFC Controller (TPZ-IFC)
  • TOPAZ Database Suite (TPZ-DBX)
  • TOPAZ Drop Option (TPZ-DRP)

The installed Topaz systems continue to be fully supported by the company. Fluidigm will continue to offer both Service Engineering and Technical support for these products at least through June 2017.  Instrument service is available on either a Service Plan or a Time & Materials basis.  Please contact techsupport@fluidigm.com for more detail.

Additionally, the company continues to manufacture and supply the consumable items utilized for our installed systems. The major items associated with the Topaz product are the two crystallization chips:

  • 1.96 Diffraction Capable Chip (TPZ-M-1.96DC)
  • 4.96 Screening Chip (TPZ-M-4.96)

Please contact your local Sales Representative or reach us at the email address above should you have any questions.

TOPAZ® System
Overview

The TOPAZ system for protein crystallography provides a complete screen-to-beam solution.

  • High quality in situ diffraction-based screening of crystals
  • The lowest sample volume requirements
  • The most accurate crystal calling software in the industry

The TOPAZ system consists of IFCs, instrumentation, and software that simplify and automate nanoscale free interface diffusion (FID). The family of IFCs includes the 1.96 Diffraction Capable (DC) chip–which uniquely provides early access to high quality in situ X-ray diffraction data–and the 4.96 screening chip–which provides the ideal solution for ultra low volume, parallel screening.

Chips

TOPAZ chips provide the most efficient screen-to-beam solution for protein crystallization. Here are a just a few of the advantages of TOPAZ chips:

  • Free Interface Diffusion (FID) and dehydration based experiments
  • Ultra low sample volume requirements
  • Simple, easy to use workflow for setting up experiments

TOPAZ 1.96 Diffraction Capable Chip

TOPAZ 1.96 Diffraction Capable (DC) chip uses the latest advances in microfluidic technology to enable in situ data collection:

  • In situ diffraction-based screening of crystals
  • Data collection from the entire chip or chip cutouts
  • No handling of individual crystals

High quality X-ray diffraction data can now be obtained early in the screening process, enabling critical decisions to be based on data rather than just subjective assessments, such as visual quality of crystals. The 1.96 DC chip can be used to screen one sample against 96 conditions at two different mixing ratios.

TOPAZ 4.96 Screening Chip

The TOPAZ 4.96 screening chip is the ideal solution for ultra low volume, parallel screening:

  • Only one µl of each sample to screen against 96 conditions
  • Screen up to four samples in parallel
  • Ideal configuration for high throughput screening

The chip requires only one microliter of protein solution per 96-reagent screen.  It also provides the ability to pursue a small volume parallel screening approach to crystallization. The 4.96 screening chip can be used to screen up to 4 samples against 96 conditions each.

After initial crystallization conditions are identified, scaling up to diffraction-quality crystals by using vapor diffusion is made easy by following Fluidigm's recommended translation protocols.

Software

AutoInspeX II Software Suite: Crystal Vision Software

The TOPAZ system includes the most advanced protein crystallization software analysis tools in the industry. Its advantages include:

  • Best in class crystal scoring capability
  • Images that are always in focus
  • Simple, intuitive interface

Fluidigm's Crystal Vision Software dramatically improves the efficiency of crystal analysis and scoring. The image processing software uses high-resolution data to accurately score the degree of crystallization activity and, thereby, removes much of the subjective analysis burden typically placed on researchers. An entire series of experiments can be evaluated in one session, saving hours of inspection time.

Crystal Vision Software at a Glance:
Calling accuracy: < 1% false negatives
 < 5% false positives
Classification of crystals 10 x 20 micron and larger





Activity scores for the entire 96-reagent screen can be viewed in various tabular formats (Figure 1) or as color-coded layouts of the experiments (Figure 2). This global view is helpful to rapidly determine the most promising conditions for crystallization. Images for individual chambers can be magnified and viewed side-by-side to compare changes over several time points.

If you wish to schedule a software demo, please contact your local sales representative

Workflow/Specs

Workflow


 1. Prep.
Prep the IFC in the TOPAZ IFC controller.  The IFC controller will automatically close the interface valves, preventing premature mixing of samples and reagents.
gyt1.png
2. Transfer.
Pipette the samples and reagents into the appropriate wells on the frame of the chip.
gyt2.png
3. Load.
Load the samples and reagents into the chip by placing it in the TOPAZ IFC controller and selecting the "load" button on the instrument's integrated touchscreen interface.
gyt3.png
4. Image.
Image the chips automatically using the AutoInspeX II workstation according to the recommended schedule.

5. Analyze.
Analyze the results using Crystal Vision™ Software and the TOPAZ database, which provide the most accurate crystal scoring in the industry and the ability to investigate results across experiments.
