Chemical Environment

Kits and screens to optimize the chemical composition of your crystallization reagents, i.e. buffer pH, precipitant and additive composition.

 

Stock Solutions

  • JBScreen Single Stocks
    Use the same chemicals as utilized in the JBScreen family to ensure maximum reproducibility of your experiments. JBScreen Single Stocks are ready for use: the concentration is adjusted and they are sterile filtered.
 

Additives and Detergents

  • JBScreen Plus
    Additive screens that focus on small molecules which interfere with sample-sample and sample-solvent interactions, mainly based on chaotropic and kosmotropic properties.
  • Memb-PASS™ Differential Filtration Detergent Assay
    Detergent screen containing carefully selected and non-denaturing detergents for integral membrane proteins.
  • JBScreen Detergents
    Advanced detergent screens for solubilization and crystallization of hydrophobic and membrane proteins.
  • JBSolution Detergent Test Kit
    Efficient screening for suitable detergents to solubilize hydrophobic and membrane proteins.
  • JBS Solubility Kit
    Optimize the solubility of your protein sample prior to crystallization trials.
  • ADDit™
    Emerald Biosystems' small molecule and salt kit aiding the crystallization of biological macromolecules.
 

Buffers

  • JBScreen pH-2D
    Cover a broad pH-range with preset buffer systems while keeping the chemical environment constant.
  • JBScreen Buffer Kits
    pH optimization made easy - the most prominent buffers with pre-adjusted pH and sterile filtered.
  • pHat™ Buffers
    Emerald Biosystems multi-purpose 96 buffer kit of 12 different buffer systems at 8 different pHs.
