Services and Technologies

The SBSR consists of the Protein Purification unit and the Structure Determination unit. The Protein Purification unit produces homogeneous, high-quality proteins well suited for downstream biophysical studies and structure determination. The Structure Determination unit employs X-ray crystallography, Cryo-EM, and advanced AI-assisted analytical tools for structure determination and imaging.

Major equipment:

  • Glacios 200 kEV electron microscope
  • MarkIV Vitrobot
  • Pelco EasiGlow
Protein Production

The protein production facility is a fully equipped core for services ranging from cloning to expression of target genes in various cells types including bacteria, insect cells, and mammalian cells. Purified proteins are fully functional for assays and for structure determination. In addition, the facility also had equipment for protein crystallization. The facility routinely produces milligram quantities of purified proteins.
