Does this include the customary grieving period?

Hi,
Does anyone have information about how long it takes to set up a 96-
well
tray for the crystallization robots available? Besides cost per
tray and
maintenance cost, another important feature we consider is the time
for
setting up a 96-well tray. It is an important factor since we are
talking
about sub-microliter drops.
Best,
Joe

Al's Oil on the plates:
What a nightmare!!!!!!!
The oil creeps up the plate and over the sides. It dissolves
adhesives.
It makes me say bad words in multiple languages.
Bigger drops + no oil = fewer bad words.

One thing that people often overlook is that quite a lot of protein
can be lost by denaturation on the surface of the drop. This is more
significant for smaller drops. Two suggestions: (1) increase the
proportion of protein in the - technical term - teeny drop to say two
thirds and (2) cover the drops with oil eg Al's oils
(silicone/paraffin). You still get vapor diffusion though the oil ,
and you'd like to slow up equilibration. of course (2) slows up the
robotics a little, but both should be trivial to set up..
