Category EM_VITRIFICATION

Name:
'em_vitrification'

Description:

   Data items in the EM_VITRIFICATION category
  record details about the method and cryogen used in
  rapid freezing of the sample on the grid prior to its
  insertion in the electron microscope

Example:

Example 1 - based on PDB entry 1DYL and laboratory records for the structure corresponding to PDB entry 1DYL
