Collection of the buffy coat layer from whole blood is critical for detecting rare circulating cells, such as circulating tumor cells (CTCs), which are of great diagnostic and research importance. Conventional methods for buffy coat collection often have low yields, significant erythrocyte contamination, and/or high costs limiting their utility. We developed a novel, multichannel aspiration device that provides efficient buffy coat collection with minimal erythrocyte contamination. This study employed spiked-in myeloma cells to model CTCs and evaluate device performance across a range of CTC concentrations (12, 30, and 300 cells/mL). The device demonstrated high CTC recovery rates, achieving up to 98% at high CTC concentrations and 89% at low concentrations. Immunofluorescent imaging confirmed preservation of cell morphology throughout the collection process. This convenient technology offers the potential of a low-cost alternative for buffy coat collection to be utilized in a wide range of clinical and research applications.

Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
