Salt Crystal Predictor

Run this tool prior to setting up screening trials to get a prediction of which drops *might* contain salt crystals.

Where applicable, program uses most common aerobic oxidation state.

If you see crystals in these drops, treat them with extra caution, but don't rule them out!

NOTE: This is currently very basic (both the code and matrix), containing just the compounds listed in the Wikipedia solubility chart . It's probably only useful when checking metalloprotein buffers or proteins in phosphate buffer.
At this time I don't have access to a science library's facilities, so would appreciate any e-mails with more extensive solubility charts containing compounds commonly used in protein/DNA crystallography.

You can add your own screens by first reading instructions HERE, and then including the 'xls' file in the upload box.

If you wish, you can use the "Browse" and "Update" buttons to include your own screens in the dropdown list below.


Step 1:
Step 2:
Type in all the salts contained in your protein storage buffer (use full American spellings such as Aluminum Sulfate):
