Equilibration buffer contained 100 mM Hepes pH 7.6, 50 mM MgCl2, 300 mM Na2SeO4, 6% PEG8k,1.0 mM TCEP, and 20% glycerol. Note that in the drop, protein at 4.3 mg/ml was mixed with equal amounts of equilibration buffer lacking glycerol, VAPOR DIFFUSION, HANGING DROP, temperature 277K

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
