In many plate sorting applications, mass screening has been pushing the limits of cell sorters higher than their practical capability with tradeoffs of speed vs accuracy. Accurate deposition, particularly into 384-well PCR plates, is critical for the success of many studies. Furthermore, throughput has been hampered by the need for time consuming recalibration between plates. With the development of Propel Labs’ Bigfoot cell sorter, the introduction of high speed plate mechanics, coupled with innovative algorithms in firmware, has increased accuracy to > 99% while cutting the expected plate sort time by an order of magnitude over the course of multiple plate sorts. 


Bigfoot was tested with 96 and 384-well plates using the horseradish peroxidase (HRP) technique (Rodrigues & Monard, 2016) which allows the detection of single to multiple drops sorted into microtiter plates. We will review the Bigfoot Cell Sorter’s cutting-edge plate sorting features and our implementation of the HRP technique to demonstrate the instrument’s unparalleled performance.
