Growth kinetics of protein single crystals in the gel acupuncture technique

“…Our previous work on the gel acupuncture technique makes use of a simple arrangement, in which capillaries are punched in the gel layer contained in a simple glass vessel. Although this quick working arrangement is recommended for the screening of crystallization conditions, we suggest for final studies the use of the glass cassettes described above, a device we used for several years in gel growth [23]. This experimental set-up permits the easy observation of phenomena inside the capillaries by optical microscopy and enhances the mechanical stability of the technique.…”
