  1. Abstract:

    Mass-produced automated piezoelectric driven picoliter delivery systems (printer heads) are fast, inexpensive, and reliable devices that are capable of delivering a very large range of volumes and are ideally suited for high-throughput protein crystallography studies. We used this technology to set up under-oil crystallization experiments with drop sizes from the 200-nL to 3-muL volume range, commonly used in protein crystallography, and show its application in setting ultra- small (2 nL) drops, the smallest drop volume reported to date for this type of assay.
