High-Throughput Crystallization Screening Center

Our Expertise – Your Results

The High-Throughput Crystallization Screening Center performs crystal-growth screening experiments in 1,536-well microassay plates for both soluble and membrane biological macromolecules. You send the sample, we do the rest.

New Formulatrix Rock Imager has been installed!
  • The new Rock Imager for imaging low temperature experiments  is up and running!

How It Works:

From February 2000, the laboratory has been used to set up over 24 million crystallization experiments on >16,000 biological macromolecules. Nearly 2,000 laboratories worldwide have used and benefited from the service.

Imaging one of our 1,536 plates!
  • At the HTCSC 1,536 different chemical conditions are sampled representing many of the commercially available crystallization screens. Each condition is imaged visually over a period of six weeks. Second Order Non-linear Imaging of Chiral Crystals (SONICC) and UV Two Photon Excited Fluorescence (UV-TPEF) imaging of crystallization screening also take place to identify biological crystals not picked up visually or those obscured by precipitate.
  • Color images, and SONICC and UV-TPEF images are integrated with the analysis software provided as part of the service. Lead crystallization conditions can be identified and the complete set of results used to analyze the samples solubility phase diagram.
  • Current list of crystallization cocktails.

HTCSC Policies and User Fees

Commercial users please inquire about using the HTCSC by emailing sbowman@hwi.buffalo.edu or check us out on Science Exchange or scientist.com.

New at HWI Crystallization Center!

MacroscopeJ and Catalina macOS

MacroscopeJ for macOS is a 32 bit app and, starting with Catalina, no longer supported by macOS.

We are currently working on a new release which will be fully supported on Catalina.

If you have upgraded to Catalina and need MacroscopeJ immediately to view your images, please contact us at htslab@hwi.buffalo.edu to get access to the beta version of MacroscopeJ that is compatible with Catalina.

Accessing your images via the ftp server.

  • Because of recent changes for both Mac and Windows OS, we recommend using FileZilla to access and transfer images from the ftp server, as it works across platforms.
