Pi minimal Screen

Efficient crystallization screening of soluble proteins


Bulk 96 screening solutions in 10 ml aliquots
HTS 96 screening solutions delivered in a deep-well block, 1.7 ml per well
The Pi-minimal Screen was developed at the MRC Laboratory of Molecular Biology (Cambridge, UK) for efficient crystallization screening of soluble proteins [1]. The approach is based on incomplete factorial design.

The unique formulation was generated following a strategy named Pi sampling [1] in order to create novel combinations of precipitants, buffers and additives across a standard 96-condition plate layout. Thus, the diversity amongst the crystallization conditions is ideal for initial screening.

The Pi-minimal Screen includes 36 components, i.e. 12 precipitants, 12 buffers systems and 12 salts.
Buffers employed in the Pi-minimal screen are buffer systems (acid-base pairs, e.g. HEPES and HEPES sodium salt). Consequently, pH can be adjusted by mixing 2 stock solutions at different ratios during later optimizations.

The efficiency of the Pi-minimal Screen was demonstrated by the crystallization of 10 proteins before its commercialization [1].
