About

Cryo-EM is a recent Nobel Prize-winning technique for microscopy and 3D reconstruction of proteins and other biological molecules. A sample containing proteins and protein-ligand complexes is frozen in a thin film of ice and subsequently imaged in an electron microscope. The resulting microscopy data is analyzed via complex algorithms to identify the contents of the sample and solve the 3D atomic structures of the embedded protein molecules in their near-native states.

cryoSPARC™

Structura Bio's state-of-the-art cryoSPARC platform is used globally for cryo-EM data analysis and 3D reconstruction. CryoSPARC offers specially designed, proprietary algorithms for membrane proteins, ion channels, GPCRs and drug targets with ligands bound.

Non-uniform Refinement: Adaptive Regularization Improves Single-particle
Cryo-EM Reconstruction

We introduce non-uniform refinement, an algorithm based on cross-validation optimization, which automatically regularizes 3D density maps during refinement to account for spatial variability.
