Project description:The purpose of this study is to evaluate the Colorectal Balloon Tube (hereinafter referred to as COLO-BT) device, a single use, temporary intraluminal bypass device, intended to reduce contact of fecal content with an anastomotic site, following colorectal surgery (open or laparoscopic)
Project description:We developed the microfluidic-oscillatory-washing-based ChIP-Seq (MOWChIP-Seq) protocol. We achieved genome-wide mapping of histone modifications (H3K4me3 and H3K27ac) with as few as 100 cells. Moreover, the automated microfluidic platform dramatically reduced assay time and has a potential for future scale-up.
Project description:Limiting contamination of LC-MS systems and reducing downtime associated with maintenance and cleaning is essential for productivity. We developed a simple device that creates a gas curtain barrier to prevent ions entering the MS inlet. The gas can be quickly and easily applied when certain contaminant ions are known to elute. We show the device can prevent the build up of contaminants on the heated transfer capillary following >100 injections of a crude tissue lysate and improves peptide identifications. The device may provide a promising approach towards improving instrument robustness.

Project description:Microfluidic devices provide a low-input and efficient platform for single-cell RNA-seq (scRNA-Seq). Here we present microfluidic diffusion-based RNA-seq (MID-RNA-seq) for conducting scRNA-seq with a diffusion-based reagent swapping scheme. This device incorporates cell trapping, lysis, reverse transcription and PCR amplification all in one microfluidic chamber. MID-RNA-Seq provides high data quality that is comparable to existing scRNA-seq methods while implementing a simple device design that permits multiplexing. The robustness and scalability of MID-RNA-Seq device will be important for transcriptomic studies of scarce cell samples.
