How do I know in which phase of my NeXtal CubicPhase cristallisation experiment I am?
FAQ ID -2421

Sponge and cubic phase are isotropic phases, while lamellar phase is anisotropic and will refract polarized light. The other difference between sponge and cubic phase is that sponge phase contains more water, and if you obtain crystals, they will tend to be floating on top of the drop.

Note: that it is possible to obtain crystals in any of the in meso phases.

A successful setup will yield a smooth looking drop, just like crystallization in PEG. Picture can be seen on the website: http://www.qiagen.com/products/nextalcubicphaseproducts.aspx#Tabs=t1.

Note: Non-colored proteins will also be visualized.
