Screening Membrane Proteins - JBScreen Membrane

JBScreen bulk & HTS

JBScreen Membrane covers 96 of the most successful conditions for crystallization of membrane proteins. Each individual composition results from an extensive analysis of the crystallization conditions that have yielded membrane protein structures so far.

The JBScreen Membrane crystallization conditions are primarily ordered by type and concentration of the precipitant. This allows easy extraction of all relevant information for a straightforward refinement: Once you get a hit, you immediately see the effects of the neighbouring conditions. The subsequent fine tuning of preliminary hits will be much more efficient.

JBScreen Detergents perfectly complement JBScreen Membrane: This combination enables you to screen a broad range of detergents, while concentrating on the most successful crystallization conditions, making crystallization screening of membrane proteins much more efficient and less time consuming.


Bulk – 24 or 96 screening solutions in 10 ml aliquots
HTS – 96 screening solutions delivered in a deep-well block, 1.7 ml per well


Individual Conditions of all screens are available in 10 ml as well as 100 ml volumes.
