Crystal Screens

JBScreen Family

  • XP Screen
    An optimized JBScreen Basic complemented with the universal additive TEW as "glue" for protein molecules
  • JBScreen Classic
    The JBScreen Classic Kits 1-10 cover 240 (10 kits x 24 conditions each) of the most prominent conditions for protein crystallization. Their compositions result from mining of literature data of several thousands of crystallized proteins. JBScreen represents the selected statistically most successful buffers that yielded protein crystals suitable for X-ray diffraction.
  • JBScreen Basic
    Based on the classic sparse matrix crystallization screen published first by Jancarik and Kim in 1991, it contains 96 unique reagent mixtures for screening a wide range of pH and various salts and precipitants.
  • JBScreen LCP
    An LCP screen based on successfully crystallized integral membrane proteins in the Lipidic Cubic Phase.
  • JBScreen Membrane
    The optimized screen for hydrophobic and membrane proteins
  • JBScreen Kinase
    A highly effective crystallization screen based on data analyses of published kinase structures
  • JBScreen Nuc-Pro
    A highly effective sparse matrix screen based upon extensive screening of the PDB, with focus on entries by structural genomic initiatives, the BMCD and other protocols.
  • JBScreen PEG/Salt
    Efficient screening of PEG 3350 and PEG 5000 MME versus 48 different salts
  • JBScreen Pentaerythritol
    A systematic crystallization screen based on pentaerythritol polymers as precipitants developed by Ulrike Demmer from the Max-Planck-Institute for Biophysics in Frankfurt.
  • JBScreen PACT ++
    Systematic screen for pH, anion, cation testing in the presence of polyehtylene glycol
  • JBScreen JCSG ++
    Optimized sparse matrix screen developed by the Joint Center for Structural Genomics (JCSG)
  • Pi-Screens
    Developed at the MRC Cambridge - Crystallization Screens for soluble and integral membrane proteins based on Pi sampling strategy
  • JBScreen Wizard
    A highly effective random sparse matrix screen for crystallizing proteins, peptides, nucleic acids and macromolecular complexes
