No beads. A bacterial cel is used as a subcompartment maintaining gene and proteins together. Evidence for leakage of small molecules at high compartment density.
- High salt:
- In [[Dielh _et al._, 2006|biblio/16791214]], by pipetting up and down in 100 mM NaCl, 1 % SDS, 1 % TritonX-100 and Tris (oil: mineral, superfactant: ABIL WE09).
- In [[Kojima _et al._, 2005|biblio/16214800]], by mixing with 1M NaCl, 5 mM Tris-HCl pH 8.0, 0.5 mM EDTA (oil: mineral; superfactant: Sun Soft No. 818SK).
+ - Extraction of beads with hexane:oil 1:1, in [[Levy _et al._, 2005|biblio/16131588]] (oil: mineral, superfactant: 5.5% Span 80, 0.5% Tween 80, 0.1 % TritonX-100).
Different kinds of superfactants: TritonX-100, Span 80, Tween 80 (many articles), ABIL WE09 ([[Dielh _et al._, 2006|biblio/16791214]] and others), Sun Soft No. 818SK (polyglycerol esters of intersesterified ricinoleic acid [[Kojima _et al._, 2005|biblio/16214800]]).
